I successfully implemented a beautiful PWA installation prompt that follows the existing update notification pattern. Here's what was completed:

Todo List:

✅ PWA Install Prompt Component Created (src/components/PWAInstallPrompt.tsx):

beforeinstallprompt event handling for Android/Chrome browsers
iOS-specific installation instructions for Safari (since beforeinstallprompt isn't supported)
Local storage tracking by app version - re-shows prompt after each update as requested
Beautiful responsive UI following existing UpdateNotification design patterns
Platform detection integration with existing usePlatformContext hook
Proper TypeScript types and React hooks best practices

✅ App Integration (src/App.tsx):

Cross-Platform Support:
- Android/Chrome: Uses native beforeinstallprompt API for one-click installation
- iOS Safari: Shows manual installation instructions via alert dialog
- Desktop: Only shows when PWA installation is available
Smart Dismissal Logic:
- Tracks dismissal state per app version using localStorage
- Re-shows prompt after app updates (as requested in issue)
- Respects user preferences while encouraging installation on updates
Beautiful Design:
- Follows existing design patterns from UpdateNotification
- Uses Tailwind CSS with consistent theming
- Responsive layout with smooth animations
- Smartphone icon and clear call-to-action buttons
Robust Implementation:
- Proper error handling and loading states
- TypeScript with strict type definitions
- React hooks with proper dependency management
- Accessibility-friendly with proper ARIA attributes

The prompt will automatically appear when:

Build & Tests: ✅ All tests pass, no linting errors, formatting applied
