- Added pgvector-go dependency for vector operations. - Implemented embedding generation using OpenAI API in a new service. - Enhanced CodeSnippetRepo to support semantic search using vector similarity. - Updated CodeSnippetUsecase to generate embeddings during snippet creation. - Added methods for semantic search by workspace and general semantic search. - Improved error handling and logging for embedding generation and vector search. - Removed unnecessary debug logs in socket handlers for cleaner output. feat: enhance CodeSnippet functionality with workspacePath for improved context and semantic search feat: add embedding and workspace path fields to CodeSnippet for semantic search functionality feat: enhance SemanticSearchByWorkspace to include cosine similarity score in results feat: 优化心跳处理逻辑，支持多种数据类型 refactor: 修复日志记录 feat: add migration for embedding and workspace_path columns in code_snippets table
