Fixes uncovered by the 2026-05-22 build-config audit + the Gradle 9 +
JUnit Platform launcher requirement that just surfaced in CI:
- testRuntimeOnly junit-platform-launcher: Gradle 9 no longer auto-
injects it; tests fail with "Failed to load JUnit Platform" without
an explicit dep.
- compileSdk + targetSdk 35 -> 36: AGP 9 defaults to 36 and warns on
lower values; CI was also auto-downloading build-tools 36 at
runtime (now pre-installed in ci-android:36).
- container.image bumped to ci-android:36 to match.
- configuration-cache.problems=warn in gradle.properties: detekt 2.0-
alpha + ktlint Gradle plugin have CC compat holes; warn rather
than fail.
- androidTest dep parity: kotlin("test") + kotlinx-coroutines-test
added (was on testImplementation only).
- CI: actions/cache@v4 for ~/.gradle/{caches,wrapper} + ~/.kotlin,
keyed on gradle-wrapper.properties + libs.versions.toml + the
*.gradle.kts files. Saves ~3 min per run after warm-up.
Deferred (with trigger conditions, will land when needed): Hilt
testing artifacts + HiltTestRunner (first @HiltAndroidTest), Room
Gradle plugin + schemaDirectory (Phase 4.2), Coil 3 ImageLoader
factory sharing OkHttp (Phase 5.4), MainDispatcherRule test utility
(Phase 5.3), JUnit-5/4 split for instrumented (Phase 5+),
NetworkSecurityConfig (pre-cutover Phase 14).

M8 phase 2.1. Runs on every push to dev/main + PR to main (path-filtered
on android/**). Tag pushes (v*) additionally build a signed release APK
attached to the existing Forgejo release as minstrel-android-<tag>.apk
during the side-by-side period; that name flips to minstrel-<tag>.apk
at M8 phase 14.4 cutover.
Reuses ANDROID_KEYSTORE_B64 + STORE/KEY_PASSWORD + KEY_ALIAS secrets so
signing matches flutter.yml — Android accepts upgrade in place at cutover
without uninstall.
runs-on: flutter-ci because that's the only proven-working runner label
on this Forgejo instance with docker. Switch to android-ci once that
label gets registered.
