Complete rebrand for v1.0-simple-search branch: Directory Changes: - claude_rag/ → mini_rag/ (preserving git history) Content Changes: - Updated all imports: from claude_rag → from mini_rag - Updated all file paths: .claude-rag → .mini-rag - Updated documentation and comments - Updated configuration files and examples - Updated all tests to use mini_rag imports This ensures complete independence from Claude/Anthropic branding while maintaining all functionality and git history. Simple branch contains the basic RAG system without LLM features.
