The previous Windows implementation used System.Windows.Forms.MessageBox
which displays a blocking modal dialog requiring user interaction.
This replaces it with the native Windows.UI.Notifications.ToastNotificationManager
API (Windows 10+) which shows a non-intrusive toast notification in the corner,
consistent with macOS and Linux behavior.
- Uses native Toast API (no external dependencies like BurntToast)
- Non-blocking: notification auto-dismisses
- Graceful degradation: silently fails on older Windows versions
- Fix escaping for each platform (PowerShell: '' for quotes, AppleScript: backslash)
