The minified release build crashed on every launch before any UI:
Unable to get provider androidx.startup.InitializationProvider:
Failed to create an instance of androidx.work.impl.WorkDatabase
The home-screen widgets use Glance, which pulls in WorkManager and its
transitive Room database (room-runtime 2.2.5). Room 2.2.5's bundled keep
rule is `-keep class * extends androidx.room.RoomDatabase` — it keeps the
class but not its constructor. Under R8 full mode (AGP 9) the generated
WorkDatabase_Impl was reduced to a non-instantiable class, so Room's
reflective newInstance() threw InstantiationException at startup.
Add `-keep class * extends androidx.room.RoomDatabase { *; }` so the
generated *_Impl classes keep their constructors. Verified against the
rebuilt release APK: WorkDatabase_Impl is now PUBLIC FINAL with its
<init> present.
