Implement comprehensive context window configuration system

Add intelligent context window management for optimal RAG performance:

## Core Features
- Dynamic context sizing based on model capabilities
- User-friendly configuration menu with Development/Production/Advanced presets
- Automatic validation against model limits (qwen3:0.6b/1.7b = 32K, qwen3:4b = 131K)
- Educational content explaining context window importance for RAG

## Technical Implementation
- Enhanced LLMConfig with context_window and auto_context parameters
- Intelligent _get_optimal_context_size() method with model-specific limits
- Consistent context application across synthesizer and explorer
- YAML configuration output with helpful context explanations

## User Experience Improvements
- Clear context window display in configuration status
- Guided selection: Development (8K), Production (16K), Advanced (32K)
- Memory usage estimates and performance guidance
- Validation prevents invalid context/model combinations

## Educational Value
- Explains why default 2048 tokens fails for RAG
- Shows relationship between context size and conversation length
- Guides users toward optimal settings for their use case
- Highlights advanced capabilities (15+ results, 4000+ character chunks)

This addresses the critical issue where Ollama's default context severely
limits RAG performance, providing users with proper configuration tools
and understanding of this crucial parameter.

+# Add Context Window Configuration for Optimal RAG Performance
+
+## Problem Statement
+
+Currently, FSS-Mini-RAG uses Ollama's default context window settings, which severely limits performance:
+
+- **Default 2048 tokens** is inadequate for RAG applications
+- Users can't configure context window for their hardware/use case
+- No guidance on optimal context sizes for different models
+- Inconsistent context handling across the codebase
+- New users don't understand context window importance
+
+## Impact on User Experience
+
+**With 2048 token context window:**
+- Only 1-2 responses possible before context truncation
+- Thinking tokens consume significant context space
+- Poor performance with larger document chunks
+- Frustrated users who don't understand why responses degrade
+
+**With proper context configuration:**
+- 5-15+ responses in exploration mode
+- Support for advanced use cases (15+ results, 4000+ character chunks)
+- Better coding assistance and analysis
+- Professional-grade RAG experience
+
+## Proposed Solution
+
+### 1. Enhanced Model Configuration Menu
+Add context window selection alongside model selection with:
+- **Development**: 8K tokens (fast, good for most cases)
+- **Production**: 16K tokens (balanced performance)  
+- **Advanced**: 32K+ tokens (heavy development work)
+
+### 2. Educational Content
+Help users understand:
+- Why context window size matters for RAG
+- Hardware implications of larger contexts
+- Optimal settings for their use case
+- Model-specific context capabilities
+
+### 3. Consistent Implementation
+- Update all Ollama API calls to use consistent context settings
+- Ensure configuration applies across synthesis, expansion, and exploration
+- Validate context sizes against model capabilities
+- Provide clear error messages for invalid configurations
+
+## Technical Implementation
+
+Based on research findings:
+
+### Model Context Capabilities
+- **qwen3:0.6b/1.7b**: 32K token maximum
+- **qwen3:4b**: 131K token maximum (YaRN extended)
+
+### Recommended Context Sizes
+```yaml
+# Conservative (fast, low memory)
+num_ctx: 8192    # ~6MB memory, excellent for exploration
+
+# Balanced (recommended for most users)  
+num_ctx: 16384   # ~12MB memory, handles complex analysis
+
+# Advanced (heavy development work)
+num_ctx: 32768   # ~24MB memory, supports large codebases
+```
+
+### Configuration Integration
+- Add context window selection to TUI configuration menu
+- Update config.yaml schema with context parameters
+- Implement validation for model-specific limits
+- Provide migration for existing configurations
+
+## Benefits
+
+1. **Improved User Experience**
+   - Longer conversation sessions
+   - Better analysis quality
+   - Clear performance expectations
+
+2. **Professional RAG Capability**
+   - Support for enterprise-scale projects
+   - Handles large codebases effectively
+   - Enables advanced use cases
+
+3. **Educational Value**
+   - Users learn about context windows
+   - Better understanding of RAG performance
+   - Informed decision making
+
+## Implementation Plan
+
+1. **Phase 1**: Research Ollama context handling (✅ Complete)
+2. **Phase 2**: Update configuration system
+3. **Phase 3**: Enhance TUI with context selection
+4. **Phase 4**: Update all API calls consistently
+5. **Phase 5**: Add documentation and validation
+
+## Questions for Review
+
+1. Should we auto-detect optimal context based on available memory?
+2. How should we handle model changes that affect context capabilities?
+3. Should context be per-model or global configuration?
+4. What validation should we provide for context/model combinations?
+
+---
+
+**This PR will significantly improve FSS-Mini-RAG's performance and user experience by properly configuring one of the most critical parameters for RAG systems.**
