Summary

Upgrades all AndroidX Lifecycle artifacts from 2.7.0 to 2.8.7, as proposed in #192.

All five artifacts pinned to Versions.androidLifecycleGrouped move together: lifecycle-viewmodel-compose, lifecycle-viewmodel-ktx, lifecycle-livedata-ktx, lifecycle-runtime-ktx, lifecycle-viewmodel-savedstate.

This lands after the Compose BOM PR on purpose: Lifecycle 2.8.x is compiled against Compose 1.7, so sequencing it after #204 avoids the known LocalLifecycleOwner runtime incompatibility with Compose 1.6.

The issue's suggestion to migrate DisposableEffect(lifecycleOwner) call sites to the new LifecycleEventEffect/LifecycleResumeEffect APIs is left as a follow-up — no behavioral change is bundled into this version bump.

Closes #192

Verification

  • ./gradlew ktfmtCheck assembleDebug testDebugUnitTest passes locally (JDK 17, SDK 35)

- Bump kotlin-gradle-plugin 1.9.22 -> 2.1.20 (root + buildSrc)
- Adopt the new Compose Compiler Gradle plugin
  (org.jetbrains.kotlin.plugin.compose) in app and convention plugins
- Drop composeCompiler version constant and composeOptions blocks
- Replace removed -Xopt-in flag with -opt-in
- Bump KSP to 2.1.20-1.0.31 to match Kotlin

Fixes Gurupreet#182
ktfmt-gradle 0.12.0 fails with 'Generic error during file processing'
once Kotlin 2.x is on the buildscript classpath. 0.22.0 supports
Kotlin 2.x and also formats *.kts build scripts, hence the repo-wide
reformat (no functional changes).

- AGP 8.2.2 -> 8.7.3 (compileSdk 35 supported from AGP 8.6)
- Gradle wrapper 8.5 -> 8.9 (required by AGP 8.7.x)
- PinLockView: removeLast() -> removeAt(lastIndex); at compileSdk 35 the
  call binds to java.util.List#removeLast (API 35) instead of the Kotlin
  stdlib extension, failing lint NewApi against minSdk 25

Fixes Gurupreet#185
- Replace compose/material3 version constants with composeBom
- Strip explicit versions from BOM-managed artifacts
- Import the BOM platform on every configuration that receives
  Compose artifacts (implementation, debugImplementation,
  androidTestImplementation, :data)
- Migrate API removals that come with Compose 1.7 / Material3 1.3:
  SmallTopAppBar -> TopAppBar, rememberRipple -> material3 ripple
- Update the outdated README Compose badge to the BOM version

Fixes Gurupreet#186
All lifecycle artifacts (viewmodel-compose, viewmodel-ktx,
livedata-ktx, runtime-ktx, viewmodel-savedstate) move together
via the shared androidLifecycleGrouped version.
