feat: add close confirmation modal with minimize to tray option

Implemented a confirmation modal when users try to close the application:
- Modal always shows with three options: Cancel, Minimize to Tray, Close Application
- Detects if Claude is actively running and shows appropriate warning message
- Removed minimize_to_tray config setting (no longer needed)
- Added core:window:allow-hide permission for window hiding
- Created CloseAppConfirmModal component with keyboard shortcuts (Escape to cancel)
- Added close_application command to properly exit the app
- Backend emits window-close-requested event for frontend to handle

This provides better UX by giving users clear choices every time they close,
preventing accidental closures during active work sessions.
