v1.18.9 Enhanced process management and resource cleanup

Fixed

• Process Management: Enhanced graceful shutdown mechanism for MCP server

  • Added comprehensive signal handlers (SIGINT, SIGTERM, SIGHUP)
  • Added Windows-specific shutdown message handling
  • Added uncaught exception and unhandled rejection handlers
  • Improved resource cleanup on server termination
  • Prevents orphaned processes when IDE closes unexpectedly

• Daemon Module Loading: Fixed potential unintended daemon startup

  • Improved module execution detection logic in daemon.ts
  • More strict validation to prevent daemon startup when imported as module
  • Only starts when explicitly executed as entry point
  • Prevents accidental daemon spawning in edge cases

• Resource Cleanup: Enhanced daemon watcher cleanup mechanism

  • Added fallback method for chokidar watcher cleanup (unwatch)
  • Improved watcher array cleanup with proper iteration
  • Added explicit database connection closure in daemon stop
  • Better cleanup logging for debugging
  • Resolves potential file watcher leaks on Windows

Added

• CLI Tool: New cleanup command for process management
  • devmind cleanup - Lists all DevMind-related Node.js processes
  • devmind cleanup --dry-run - Preview processes without killing
  • devmind cleanup --force - Kill processes without confirmation
  • Cross-platform support (Windows and Unix/Linux/Mac)
  • Interactive confirmation for safety
  • Emergency tool for resolving orphaned process issues

Technical Details

• Improved Windows platform compatibility for process lifecycle management
• Enhanced error handling in daemon resource cleanup
• Added defensive programming patterns to prevent edge-case process leaks
• All changes are backward compatible

Why This Update?

While the architecture was already correct (MCP server doesn't start daemon), these improvements:

1. Add defense-in-depth for process management on Windows
2. Provide users with emergency cleanup tools
3. Improve system robustness under abnormal termination scenarios
4. Ensure clean shutdown even when IDE crashes or kills processes
