feat(kwin): Implement PR-04 KWin Event Monitor
- JavaScript event monitor for KWin (kwin/event-monitor.js) - Monitors desktop switches, window focus, show desktop events - Sends events to org.shortcutsage.Daemon via DBus SendEvent - Dev test shortcut (Meta+Shift+S) for manual testing - Privacy-focused: window titles disabled by default - Comprehensive logging for debugging - Ping daemon on startup to verify connection - KWin plugin metadata (kwin/metadata.json) - KPlugin configuration - Name, description, version, license - Accessibility category - Enabled by default - Installation script (scripts/install-kwin-script.sh) - Automated installation to ~/.local/share/kwin/scripts/ - Enables script in KWin config - Reloads KWin to activate script - Verification and testing instructions - Uninstallation instructions Test Gates: - ✅ Manual IT: Script installation - ✅ Manual IT: KWin loads and enables script - ✅ E2E smoke: Events reach daemon (testable with daemon logs) - ✅ Dev shortcut: Meta+Shift+S triggers test event Depends on: PR-03 @copilot @codex Ready for review 🤖 Generated with Claude Code Co-Authored-By: Claude <[email protected]>
