Multi-platform export: Anpfiff1 is going everywhere

Big plans for Anpfiff1:

So far it has been Android only. That is changing.

Planned platforms:
- iOS (top priority)
- Windows desktop
- Linux, Steam Deck compatible
- macOS

The technical work:
- Platform-specific adjustments
- A build pipeline that covers all of them
- Input handling for touch, mouse, keyboard and gamepad

✅ Cloud saves will work across platforms
✅ Highscores stay shared between them
