glasses: switch to rikka.shizuku.ShizukuProvider, fix binder acquisition

- Add dev.rikka.shizuku:provider:13.1.5 dependency.
- Replace custom ShizukuInitProvider with rikka.shizuku.ShizukuProvider
  from the upstream library; configured per Shizuku v12+ docs with
  android:permission='android.permission.INTERACT_ACROSS_USERS_FULL'
  to protect the provider from ordinary apps.
- Move ShizukuBootstrap.attach() from GlassesVmApp.onCreate to
  MainActivity.onCreate (requestPermission needs an Activity context).
- MainActivity now overrides onRequestPermissionsResult and forwards
  the grant to ShizukuBootstrap.
- Rewrite ShizukuBootstrap strictly per the Shizuku-API guide:
  addBinderReceivedListenerSticky + addRequestPermissionResultListener
  in attach(); pingBinder / checkSelfPermission / requestPermission
  in refresh().
- Drop ShizukuInitProvider.kt — its job is now done by
  rikka.shizuku.ShizukuProvider.onCreate (verified in logcat:
  'ShizukuProvider: binder received').

Verified on device ARGF20 (A06B4AB933C4103, API 32): Shizuku dialog
'Allow rayneo-vm to use Shizuku?' opens correctly; binder received
via ShizukuProvider; launcher icon now visible (meta-data fix).
