fix(mcp-kb): add input validation, path security, and health checks
...
Security fixes from deep review:
- Add input validation patterns for project_id, agent_id, collection
- Add path traversal protection for source_path (reject .., null bytes)
- Add error codes (INTERNAL_ERROR) to generic exception handlers
- Handle FieldInfo objects in validation for test robustness
Performance fixes:
- Enable concurrent hybrid search with asyncio.gather
Health endpoint improvements:
- Check all dependencies (database, Redis, LLM Gateway)
- Return degraded/unhealthy status based on dependency health
- Updated tests for new health check response structure
All 139 tests pass.

feat(knowledge-base): implement Knowledge Base MCP Server ( #57 )
...
Implements RAG capabilities with pgvector for semantic search:
- Intelligent chunking strategies (code-aware, markdown-aware, text)
- Semantic search with vector similarity (HNSW index)
- Keyword search with PostgreSQL full-text search
- Hybrid search using Reciprocal Rank Fusion (RRF)
- Redis caching for embeddings
- Collection management (ingest, search, delete, stats)
- FastMCP tools: search_knowledge, ingest_content, delete_content,
list_collections, get_collection_stats, update_document
Testing:
- 128 comprehensive tests covering all components
- 58% code coverage (database integration tests use mocks)
- Passes ruff linting and mypy type checking
