build: update to Gradle 9.8.2, AGP 9.5.0, Kotlin 2.4.21, Hilt 2.60.1

AGP 9 migration:
- Configure the shared Android setup through the new DSL
  (CommonExtension, ApplicationExtension) instead of the removed
  TestedExtension and BaseAppModuleExtension; targetSdk moves to the
  application extension.
- Stop applying the Kotlin Android plugin; AGP 9 compiles Kotlin itself.
- Replace kapt with KSP 2.3.13 for Hilt, which built-in Kotlin requires,
  and carry the Dagger compiler options over as KSP arguments.
- AGP 9 now applies packaging excludes to unit-test resources, which
  stripped the diceware word list (**/*.txt) from its tests; lift that
  exclude in the diceware module.
- Use resources.directories instead of the deprecated srcDir.

Plugin updates required by Gradle 9 / AGP 9: Sentry Gradle plugin
6.25.0 (sentry-android 8.62.0), metalava plugin 0.5.1, maven-publish
0.37.0, spotless 8.10.4, version-catalog-update 1.1.2, download task
5.7.0, foojay resolver 1.0.0, with their API changes. Newer metalava
models Kotlin properties, so autofill-parser/api.txt is regenerated;
the diff is representation only, no API was added or removed.

Fix new Kotlin 2.4 and lint findings (explicit return type in a
function with an early return, UseKtx in autofill-parser), drop
deprecated Kotlin Gradle properties, and make the AGENTS.md pre-commit
command cover every task CI runs (both flavors, lint on all modules).
