David Blanc Brioir ad2c29a777 Fix Library RAG MCP connection issue and add setup documentation ...

Problem:
- Library RAG MCP server was failing to connect with timeout error
- Backend status showed "connected: false" with "MCP error -32001: Request timed out"
- Documents uploaded via upload_document tool were never processed

Root Cause:
- MISTRAL_API_KEY was commented out in .env file
- MCP server requires this key for OCR and LLM processing
- Without the key, the Python subprocess fails to start
- This caused connection timeout in the Node.js backend

Solution:
- Uncommented MISTRAL_API_KEY in .env (not committed, in .gitignore)
- Added LIBRARY_RAG_SETUP.md with complete setup guide
- Updated .claude/settings.local.json with bash permissions

Changes:
- Added LIBRARY_RAG_SETUP.md (setup documentation)
- Updated .claude/settings.local.json (auto-approved bash commands)

Verified:
- MCP server now connects successfully
- Status endpoint shows "connected: true"
- All 7 Library RAG tools available (upload_document, search_library, etc.)
