- Store URL changed from https://play.google.com to market:// so the
  Play Store app opens directly instead of a browser
- Falls back to https://play.google.com if Play Store is not installed
- Added <queries> block to AndroidManifest for market:// and
  play.google.com — required for launchUrl to work on Android 11+
  (package visibility restrictions silently blocked it before)
