Added codebase search and retrieval to Vectorstore

Summary indexing: Added functionality to embed and index file summaries from file_summaries.json in Pinecone
Vector search: Implemented semantic search to find the top 5 most relevant files for a query
Content retrieval: Added method to fetch full file content from file_content.json
API endpoints:
/getFileSummaries - Retrieves all file summaries
/getFileContent - Fetches file content by path
/getRawFileContent - Returns content as plain text to avoid JSON parsing errors
Error handling: Added comprehensive error handling and debugging throughout
Initialization: Implemented proper async initialization sequence with verification
Performance: Added streaming for large files to improve memory efficiency
Testing: Added automated test queries to validate functionality
