Migrate `PackageManager.getInstalledPackages`

[Goooler]

PackageManager.getInstalledPackages(PackageManager.GET_PERMISSIONS) uses the deprecated flags-based API on newer SDKs. Since this module compiles against recent Android SDKs, prefer the PackageInfoFlags overload on API 33+ (and keep a compat branch for older APIs) to avoid deprecation warnings and future breakage.

PackageManager.queryIntentActivities(Intent, Int) is deprecated on newer SDKs (compileSdk is high in this repo). To avoid deprecation warnings and keep behavior consistent, use the ResolveInfoFlags overload on API 33+ (and fall back to the old call on older APIs).
