* feat(core): Add AST-aware code chunking with astchunk integration This PR introduces intelligent code chunking that preserves semantic boundaries (functions, classes, methods) for better code understanding in RAG applications. Key Features: - AST-aware chunking for Python, Java, C#, TypeScript files - Graceful fallback to traditional chunking for unsupported languages - New specialized code RAG application for repositories - Enhanced CLI with --use-ast-chunking flag - Comprehensive test suite with integration tests Technical Implementation: - New chunking_utils.py module with enhanced chunking logic - Extended base RAG framework with AST chunking arguments - Updated document RAG with --enable-code-chunking flag - CLI integration with proper error handling and fallback Benefits: - Better semantic understanding of code structure - Improved search quality for code-related queries - Maintains backward compatibility with existing workflows - Supports mixed content (code + documentation) seamlessly Dependencies: - Added astchunk and tree-sitter parsers to pyproject.toml - All dependencies are optional - fallback works without them Testing: - Comprehensive test suite in test_astchunk_integration.py - Integration tests with document RAG - Error handling and edge case coverage Documentation: - Updated README.md with AST chunking highlights - Added ASTCHUNK_INTEGRATION.md with complete guide - Updated features.md with new capabilities * Refactored chunk utils * Remove useless import * Update README.md * Update apps/chunking/utils.py Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update apps/code_rag.py Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Fix issue * apply suggestion from @Copilot Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Fixes after pr review * Fix tests not passing * Fix linter error for documentation files * Update .gitignore with unwanted files --------- Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> Co-authored-by: Andy Lee <andylizf@outlook.com>
