feat: implement graph-based indexing with semantic chunking
- Add graph-based index interfaces for hierarchical code relationships - Implement GraphIndexStore using Qdrant for node and edge storage - Create RelationshipExtractor to analyze AST and extract code relationships - Add ContextAwareSearchService for enhanced retrieval with relationship traversal - Implement SemanticParser for intelligent code chunking based on AST analysis - Support multiple languages (TypeScript, JavaScript, Python, etc.) - Enable context-aware search with call chains and dependency trees This enhancement provides better codebase understanding through: - Hierarchical indexing of code elements (classes, functions, imports, etc.) - Graph-based relationships between code components - Semantic chunking that respects code structure - Context-aware retrieval that includes related code
