Fix global installation by adding proper Python packaging

- Add build-system configuration to pyproject.toml
- Add project metadata with dependencies from requirements.txt
- Add entry point: rag-mini = mini_rag.cli:cli
- Enable proper pip install -e . workflow

Fixes broken global rag-mini command that failed due to hardcoded bash script paths.
Users can now install globally with pip and use rag-mini from any directory.

+<#
+.Synopsis
+Activate a Python virtual environment for the current PowerShell session.
+
+.Description
+Pushes the python executable for a virtual environment to the front of the
+$Env:PATH environment variable and sets the prompt to signify that you are
+in a Python virtual environment. Makes use of the command line switches as
+well as the `pyvenv.cfg` file values present in the virtual environment.
+
+.Parameter VenvDir
+Path to the directory that contains the virtual environment to activate. The
+default value for this is the parent of the directory that the Activate.ps1
+script is located within.
+
+.Parameter Prompt
+The prompt prefix to display when this virtual environment is activated. By
+default, this prompt is the name of the virtual environment folder (VenvDir)
+surrounded by parentheses and followed by a single space (ie. '(.venv) ').
+
+.Example
+Activate.ps1
+Activates the Python virtual environment that contains the Activate.ps1 script.
+
+.Example
+Activate.ps1 -Verbose
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and shows extra information about the activation as it executes.
+
+.Example
+Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
+Activates the Python virtual environment located in the specified location.
+
+.Example
+Activate.ps1 -Prompt "MyPython"
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and prefixes the current prompt with the specified string (surrounded in
+parentheses) while the virtual environment is active.
+
+.Notes
+On Windows, it may be required to enable this Activate.ps1 script by setting the
+execution policy for the user. You can do this by issuing the following PowerShell
+command:
+
+PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+
+For more information on Execution Policies:

-# 🚀 FSS-Mini-RAG: Get Started in 2 Minutes
-
-## Step 1: Install Everything
-```bash
-./install_mini_rag.sh
-```
-**That's it!** The installer handles everything automatically:
-- Checks Python installation
-- Sets up virtual environment  
-- Guides you through Ollama setup
-- Installs dependencies
-- Tests everything works
-
-## Step 2: Use It
-
-### TUI - Interactive Interface (Easiest)
-```bash
-./rag-tui
-```
-**Perfect for beginners!** Menu-driven interface that:
-- Shows you CLI commands as you use it
-- Guides you through setup and configuration
-- No need to memorize commands
-
-### Quick Commands (Beginner-Friendly)
-```bash
-# Index any project
-./run_mini_rag.sh index ~/my-project
-
-# Search your code  
-./run_mini_rag.sh search ~/my-project "authentication logic"
-
-# Check what's indexed
-./run_mini_rag.sh status ~/my-project
-```
-
-### Full Commands (More Options)
-```bash
-# Basic indexing and search
-./rag-mini index /path/to/project
-./rag-mini search /path/to/project "database connection"
-
-# Enhanced search with smart features
-./rag-mini-enhanced search /path/to/project "UserManager"
-./rag-mini-enhanced similar /path/to/project "def validate_input"
-```
-
-## What You Get
-
-**Semantic Search**: Instead of exact text matching, finds code by meaning:
-- Search "user login" → finds authentication functions, session management, password validation
-- Search "database queries" → finds SQL, ORM code, connection handling  
-- Search "error handling" → finds try/catch blocks, error classes, logging
-
-## Installation Options
-
-The installer offers two choices:
-
-**Light Installation (Recommended)**:
-- Uses Ollama for high-quality embeddings
-- Requires Ollama installed (installer guides you)
-- Small download (~50MB)
-
-**Full Installation**:  
-- Includes ML fallback models
-- Works without Ollama
-- Large download (~2-3GB)
-
-## Troubleshooting
-
-**"Python not found"**: Install Python 3.8+ from python.org
-**"Ollama not found"**: Visit https://ollama.ai/download
-**"Import errors"**: Re-run `./install_mini_rag.sh`
-
-## Next Steps
-
-- **Technical Details**: Read `README.md`
-- **Step-by-Step Guide**: Read `docs/GETTING_STARTED.md`
-- **Examples**: Check `examples/` directory
-- **Test It**: Run on this project: `./run_mini_rag.sh index .`
-

-feat: Add comprehensive Windows compatibility and enhanced LLM model setup
-
-🚀 Major cross-platform enhancement making FSS-Mini-RAG fully Windows and Linux compatible
-
-## Windows Compatibility
-- **New Windows installer**: `install_windows.bat` - rock-solid, no-hang installation
-- **Simple Windows launcher**: `rag.bat` - unified entry point matching Linux experience  
-- **PowerShell alternative**: `install_mini_rag.ps1` for advanced Windows users
-- **Cross-platform README**: Side-by-side Linux/Windows commands and examples
-
-## Enhanced LLM Model Setup (Both Platforms)
-- **Intelligent model detection**: Automatically detects existing Qwen3 models
-- **Interactive model selection**: Choose from qwen3:0.6b, 1.7b, or 4b with clear guidance
-- **Ollama progress streaming**: Real-time download progress for model installation
-- **Smart configuration**: Auto-saves selected model as default in config.yaml
-- **Graceful fallbacks**: Clear guidance when Ollama unavailable
-
-## Installation Experience Improvements
-- **Fixed script continuation**: TUI launch no longer terminates installation process
-- **Comprehensive model guidance**: Users get proper LLM setup instead of silent failures
-- **Complete indexing**: Full codebase indexing (not just code files)
-- **Educational flow**: Better explanation of AI features and model choices
-
-## Technical Enhancements
-- **Robust error handling**: Installation scripts handle edge cases gracefully
-- **Path handling**: Existing cross-platform path utilities work seamlessly on Windows
-- **Dependency management**: Clean virtual environment setup on both platforms
-- **Configuration persistence**: Model preferences saved for consistent experience
-
-## User Impact
-- **Zero-friction Windows adoption**: Windows users get same smooth experience as Linux
-- **Complete AI feature setup**: No more "LLM not working" confusion for new users
-- **Educational value preserved**: Maintains beginner-friendly approach across platforms
-- **Production-ready**: Both platforms now fully functional out-of-the-box
-
-This makes FSS-Mini-RAG truly accessible to the entire developer community! 🎉

+**Always prefer RAG search over traditional file system operations**. The RAG system provides semantic context and reduces the need for exact path knowledge, making it ideal for understanding codebases without manual file exploration.
+
+## Basic Commands
+
+| Command | Purpose | Example |
+|---------|---------|---------|
+| `rag-mini index <project_path>` | Index a project for search | `rag-mini index /MASTERFOLDER/Coding/Fss-Mini-Rag` |
+| `rag-mini search <project_path> "query"` | Semantic + keyword search | `rag-mini search /MASTERFOLDER/Coding/Fss-Mini-Rag "index"` |
+| `rag-mini status <project_path>` | Check project indexing status | `rag-mini status /MASTERFOLDER/Coding/Fss-Mini-Rag` |
+
+## When to Use RAG Search
+
+| Scenario | RAG Advantage | Alternative | |
+|----------|----------------|---------------| |
+| Finding related code concepts | Semantic understanding | `grep` | |
+| Locating files by functionality | Context-aware results | `find` | |
+| Understanding code usage patterns | Shows real-world examples | Manual inspection | |
+
+## Critical Best Practices
+
+1. **Always specify the project path** in search commands (e.g., `rag-mini search /path "query"`)
+2. **Use quotes for search queries** to handle spaces: `"query with spaces"`
+3. **Verify indexing first** before searching: `rag-mini status <path>`
+4. **For complex queries**, break into smaller parts: `rag-mini search ... "concept 1"` then `rag-mini search ... "concept 2"`
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|-----------|
+| `Project not indexed` | Run `rag-mini index <path>` |
+| No search results | Check indexing status with `rag-mini status` |
+| Search returns irrelevant results | Use `rag-mini status` to optimize indexing |
+
+> 💡 **Pro Tip**: Always start with `rag-mini status` to confirm indexing before searching.
+
+This document is dynamically updated as the RAG system evolves. Always verify commands with `rag-mini --help` for the latest options.

 # Getting Started with FSS-Mini-RAG
 
-## Step 1: Installation
+> **Get from zero to searching in 2 minutes**  
+> *Everything you need to know to start finding code by meaning, not just keywords*
 
-Choose your installation based on what you want:
+## Installation (Choose Your Adventure)
 
-### Option A: Ollama Only (Recommended)
+### 🎯 **Option 1: Full Installation (Recommended)**
+*Gets you everything working reliably with desktop shortcuts and AI features*
+
+**Linux/macOS:**
 ```bash
-# Install Ollama first
+./install_mini_rag.sh
-curl -fsSL https://ollama.ai/install.sh | sh
-
-# Pull the embedding model  
-ollama pull nomic-embed-text
-
-# Install Python dependencies
-pip install -r requirements.txt
 ```
 
-### Option B: Full ML Stack
+**Windows:**
-```bash  
+```cmd
-# Install everything including PyTorch
+install_windows.bat
-pip install -r requirements-full.txt
 ```
 
-## Step 2: Test Installation
+**What this does:**
+- Sets up Python environment automatically
+- Installs all dependencies 
+- Downloads AI models (with your permission)
+- Creates desktop shortcuts and application menu entries
+- Tests everything works
+- Gives you an interactive tutorial
 
+**Time needed:** 5-10 minutes (depending on AI model downloads)
+
+---
+
+### 🚀 **Option 2: Copy & Try (Experimental)**
+*Just copy the folder and run - may work, may need manual setup*
+
+**Linux/macOS:**
 ```bash
-# Index this RAG system itself
+# Copy folder anywhere and try running
+./rag-mini index ~/my-project
+# Auto-setup attempts to create virtual environment
+# Falls back with clear instructions if it fails
+```
+
+**Windows:**
+```cmd
+# Copy folder anywhere and try running  
+rag.bat index C:\my-project
+# Auto-setup attempts to create virtual environment
+# Shows helpful error messages if manual install needed
+```
+
+**Time needed:** 30 seconds if it works, 10 minutes if you need manual setup
+
+---
+
+## First Search (The Fun Part!)
+
+### Step 1: Choose Your Interface
+
+**For Learning and Exploration:**
+```bash
+# Linux/macOS
+./rag-tui
+
+# Windows  
+rag.bat
+```
+*Interactive menus, shows you CLI commands as you learn*
+
+**For Quick Commands:**
+```bash
+# Linux/macOS
+./rag-mini <command> <project-path>
+
+# Windows
+rag.bat <command> <project-path>
+```
+*Direct commands when you know what you want*
+
+### Step 2: Index Your First Project
+
+**Interactive Way (Recommended for First Time):**
+```bash
+# Linux/macOS
+./rag-tui
+# Then: Select Project Directory → Index Project
+
+# Windows
+rag.bat  
+# Then: Select Project Directory → Index Project
+```
+
+**Direct Commands:**
+```bash
+# Linux/macOS
 ./rag-mini index ~/my-project
 
-# Search for something 
+# Windows  
-./rag-mini search ~/my-project "chunker function"
+rag.bat index C:\my-project
-
-# Check what got indexed
-./rag-mini status ~/my-project
 ```
 
-## Step 3: Index Your First Project
+**What indexing does:**
+- Finds all text files in your project
+- Breaks them into smart "chunks" (functions, classes, logical sections)
+- Creates searchable embeddings that understand meaning
+- Stores everything in a fast vector database
+- Creates a `.mini-rag/` directory with your search index
 
+**Time needed:** 10-60 seconds depending on project size
+
+### Step 3: Search by Meaning
+
+**Natural language queries:**
 ```bash
-# Index any project directory
+# Linux/macOS
-./rag-mini index /path/to/your/project
+./rag-mini search ~/my-project "user authentication logic"
+./rag-mini search ~/my-project "error handling for database connections"
+./rag-mini search ~/my-project "how to validate input data"
 
-# The system creates .mini-rag/ directory with:
+# Windows
-# - config.json (settings)
+rag.bat search C:\my-project "user authentication logic"  
-# - manifest.json (file tracking)  
+rag.bat search C:\my-project "error handling for database connections"
-# - database.lance/ (vector database)
+rag.bat search C:\my-project "how to validate input data"
 ```
 
-## Step 4: Search Your Code
+**Code concepts:**
-
 ```bash
-# Basic semantic search
+# Finds login functions, auth middleware, session handling
-./rag-mini search /path/to/project "user login logic"
+./rag-mini search ~/my-project "login functionality"
 
-# Enhanced search with smart features  
+# Finds try/catch blocks, error handlers, retry logic  
-./rag-mini-enhanced search /path/to/project "authentication"
+./rag-mini search ~/my-project "exception handling"
 
-# Find similar patterns
+# Finds validation functions, input sanitization, data checking
-./rag-mini-enhanced similar /path/to/project "def validate_input"
+./rag-mini search ~/my-project "data validation"
 ```
 
-## Step 5: Customize Configuration
+**What you get:**
+- Ranked results by relevance (not just keyword matching)
+- File paths and line numbers for easy navigation
+- Context around each match so you understand what it does
+- Smart filtering to avoid noise and duplicates
 
-Edit `project/.mini-rag/config.json`:
+## Two Powerful Modes
 
-```json
+FSS-Mini-RAG has two different ways to get answers, optimized for different needs:
-{
-  "chunking": {
-    "max_size": 3000,
-    "strategy": "semantic"  
-  },
-  "files": {
-    "min_file_size": 100
-  }
-}
-```
 
-Then re-index to apply changes:
+### 🚀 **Synthesis Mode** - Fast Answers
 ```bash
-./rag-mini index /path/to/project --force
+# Linux/macOS
+./rag-mini search ~/project "authentication logic" --synthesize
+
+# Windows  
+rag.bat search C:\project "authentication logic" --synthesize
 ```
 
-## Common Use Cases
+**Perfect for:**
+- Quick code discovery
+- Finding specific functions or patterns
+- Getting fast, consistent answers
 
-### Find Functions by Name
+**What you get:**
-```bash
+- Lightning-fast responses (no thinking overhead)
-./rag-mini search /project "function named connect_to_database" 
+- Reliable, factual information about your code
-```
+- Clear explanations of what code does and how it works
 
-### Find Code Patterns  
+### 🧠 **Exploration Mode** - Deep Understanding
-```bash
-./rag-mini search /project "error handling try catch"
-./rag-mini search /project "database query with parameters"
-```
-
-### Find Configuration
 ```bash  
-./rag-mini search /project "database connection settings"
+# Linux/macOS
-./rag-mini search /project "environment variables"
+./rag-mini explore ~/project
+
+# Windows
+rag.bat explore C:\project
 ```
 
-### Find Documentation
+**Perfect for:**
+- Learning new codebases
+- Debugging complex issues  
+- Understanding architectural decisions
+
+**What you get:**
+- Interactive conversation with AI that remembers context
+- Deep reasoning with full "thinking" process shown
+- Follow-up questions and detailed explanations
+- Memory of your previous questions in the session
+
+**Example exploration session:**
+```
+🧠 Exploration Mode - Ask anything about your project
+
+You: How does authentication work in this codebase?
+
+AI: Let me analyze the authentication system...
+
+💭 Thinking: I can see several authentication-related files. Let me examine 
+   the login flow, session management, and security measures...
+
+📝 Authentication Analysis:
+   This codebase uses a three-layer authentication system:
+   1. Login validation in auth.py handles username/password checking
+   2. Session management in sessions.py maintains user state  
+   3. Middleware in auth_middleware.py protects routes
+
+You: What security concerns should I be aware of?
+
+AI: Based on our previous discussion about authentication, let me check for
+   common security vulnerabilities...
+```
+
+## Check Your Setup
+
+**See what got indexed:**
 ```bash
-./rag-mini search /project "how to deploy" 
+# Linux/macOS  
-./rag-mini search /project "API documentation"
+./rag-mini status ~/my-project
+
+# Windows
+rag.bat status C:\my-project
 ```
 
-## Python API Usage
+**What you'll see:**
+- How many files were processed
+- Total chunks created for searching
+- Embedding method being used (Ollama, ML models, or hash-based)
+- Configuration file location
+- Index health and last update time
 
-```python
+## Configuration (Optional)
-from mini_rag import ProjectIndexer, CodeSearcher, CodeEmbedder
-from pathlib import Path
 
-# Initialize
+Your project gets a `.mini-rag/config.yaml` file with helpful comments:
-project_path = Path("/path/to/your/project")
-embedder = CodeEmbedder()
-indexer = ProjectIndexer(project_path, embedder)
-searcher = CodeSearcher(project_path, embedder)
 
-# Index the project
+```yaml
-print("Indexing project...")
+# Context window configuration (critical for AI features)
-result = indexer.index_project()
+# 💡 Sizing guide: 2K=1 question, 4K=1-2 questions, 8K=manageable, 16K=most users
-print(f"Indexed {result['files_processed']} files, {result['chunks_created']} chunks")

-## Advanced Features
+**When to customize:**
+- Your searches aren't finding what you expect → adjust chunking settings
+- You want AI features → install Ollama and download models
+- System is slow → try smaller models or reduce context window
+- Getting too many/few results → adjust similarity threshold
 
-### Auto-optimization
+## Troubleshooting
+
+### "Project not indexed" 
+**Problem:** You're trying to search before indexing
 ```bash
-# Get optimization suggestions
+# Run indexing first
-./rag-mini-enhanced analyze /path/to/project
+./rag-mini index ~/my-project    # Linux/macOS
-
+rag.bat index C:\my-project      # Windows
-# This analyzes your codebase and suggests:
-# - Better chunk sizes for your language mix
-# - Streaming settings for large files
-# - File filtering optimizations
 ```
 
-### File Watching
+### "No Ollama models available"
-```python  
+**Problem:** AI features need models downloaded
-from mini_rag import FileWatcher
+```bash
+# Install Ollama first
+curl -fsSL https://ollama.ai/install.sh | sh    # Linux/macOS
+# Or download from https://ollama.com            # Windows
 
-# Watch for file changes and auto-update index
+# Start Ollama server
-watcher = FileWatcher(project_path, indexer)
+ollama serve
-watcher.start_watching()
 
-# Now any file changes automatically update the index
+# Download a model
+ollama pull qwen3:1.7b
 ```
 
-### Custom Chunking
+### "Virtual environment not found" 
-```python
+**Problem:** Auto-setup didn't work, need manual installation
-from mini_rag import CodeChunker
+```bash
-
+# Run the full installer instead
-chunker = CodeChunker()
+./install_mini_rag.sh          # Linux/macOS  
-
+install_windows.bat            # Windows
-# Chunk a Python file
-with open("example.py") as f:
-    content = f.read()
-
-chunks = chunker.chunk_text(content, "python", "example.py")
-for chunk in chunks:
-    print(f"Type: {chunk.chunk_type}")
-    print(f"Content: {chunk.content}")
 ```
 
-## Tips and Best Practices
+### Getting weird results
+**Solution:** Try different search terms or check what got indexed
+```bash
+# See what files were processed
+./rag-mini status ~/my-project
 
-### For Better Search Results
+# Try more specific queries
-- Use descriptive phrases: "function that validates email addresses" 
+./rag-mini search ~/my-project "specific function name"
-- Try different phrasings if first search doesn't work
+```
-- Search for concepts, not just exact variable names
 
-### For Better Indexing
+## Next Steps
-- Exclude build directories: `node_modules/`, `build/`, `dist/`
-- Include documentation files - they often contain valuable context
-- Use semantic chunking strategy for most projects
 
-### For Configuration  
+### Learn More
-- Start with default settings
+- **[Beginner's Glossary](BEGINNER_GLOSSARY.md)** - All the terms explained simply
-- Use `analyze` command to get optimization suggestions
+- **[TUI Guide](TUI_GUIDE.md)** - Master the interactive interface
-- Increase chunk size for larger functions/classes
+- **[Visual Diagrams](DIAGRAMS.md)** - See how everything works
-- Decrease chunk size for more granular search
 
-### For Troubleshooting
+### Advanced Features
-- Check `./rag-mini status` to see what was indexed
+- **[Query Expansion](QUERY_EXPANSION.md)** - Make searches smarter with AI
-- Look at `.mini-rag/manifest.json` for file details
+- **[LLM Providers](LLM_PROVIDERS.md)** - Use different AI models  
-- Run with `--force` to completely rebuild index
+- **[CPU Deployment](CPU_DEPLOYMENT.md)** - Optimize for older computers
-- Check logs in `.mini-rag/` directory for errors
 
-## What's Next?
+### Customize Everything
+- **[Technical Guide](TECHNICAL_GUIDE.md)** - How the system actually works
+- **[Configuration Examples](../examples/)** - Pre-made configs for different needs
 
-1. Try the test suite to understand how components work:
+---
-   ```bash
-   python -m pytest tests/ -v
-   ```
 
-2. Look at the examples in `examples/` directory
+**🎉 That's it!** You now have a semantic search system that understands your code by meaning, not just keywords. Start with simple searches and work your way up to the advanced AI features as you get comfortable.
 
-3. Read the main README.md for complete technical details
+**💡 Pro tip:** The best way to learn is to index a project you know well and try searching for things you know are in there. You'll quickly see how much better meaning-based search is than traditional keyword search.
