Sets isMinifyEnabled = true and isShrinkResources = true so the release
APK/AAB passes Google Play's ≥25% obfuscation requirement.

ProGuard keep rules added for the three things R8 cannot safely rename:

  • Gson model classes (Medication, VersionInfo, LanguageData) whose field
    names must match JSON keys since Gson uses reflection
  • UpdateWorker, whose class name is resolved by string at WorkManager
    startup

Room, Retrofit, OkHttp, Compose, and WorkManager all ship their own
consumer ProGuard rules inside their AARs, so no manual rules are needed
for those libraries.
