- Add JSON format to daemon.lock with database path, version, PID, and timestamp
- Validate database path on client connection (fail if mismatch)
- Backward compatible with old plain-PID lock files
- Add comprehensive tests for JSON format and validation
- Update all lock acquisition callsites to pass database path

- Write PID to daemon.pid when acquiring lock for Windows compatibility
- Increase socket cleanup timeout to 5s for Windows
- Windows can't read locked files, so PID file is required fallback
- Fix PID detection: Open lock file with O_RDWR for Windows LockFileEx
- Fix script tests: Increase timeout to 2-5s for Windows process startup
- Fix uptime test: Use math.Ceil with minimum 1 second to prevent flakiness
- Fix socket cleanup: Add done channel to wait for Start() cleanup completion
All 5 failing Windows tests should now pass.
- Implemented daemon.lock using flock (Unix) and LockFileEx (Windows)
- Lock acquired before PID file, held for daemon lifetime
- Eliminates race conditions in concurrent daemon starts
- Backward compatible: falls back to PID check for old daemons
- Updated isDaemonRunning() to check lock availability
- All tests pass including new lock and backward compatibility tests
