v1.4.1

v1.4.1 Bug Fixes & Stability Improvements

🔧 Critical Fix

• Fix process hang on Zotero exit (#31, #23): bootstrap.js now always calls onShutdown() before APP_SHUTDOWN check, ensuring HTTP server socket and SQLite database connections are properly closed. This resolves the issue where Zotero processes remained alive after closing the application.

🐛 Bug Fixes

• Fix PDF text extraction error logging: Error objects now properly display name and message instead of {}
• Fix semantic index rebuild loop: Items with empty content are now marked in index_status to prevent repeated extraction attempts
• Fix SemanticColumn cache refresh storm: Added mutex flag to prevent 60+ concurrent cache refresh calls (reduced to 1)

✨ New Features

• Semantic search toggle: Added enable/disable checkbox in preferences UI to control semantic search functionality
• Semantic tools guard: MCP server filters out semantic tools when semantic search is disabled

📝 Other Changes

• Updated Claude Code config to use CLI command format (claude mcp add)
• Added process lifecycle diagnostic logging (PID, processType) for startup/shutdown
• Updated WeChat group QR code image
