Target Android 16 (API 36)

[75py]

Summary

• target Android 16 by moving compileSdk and targetSdk to 36 and preparing version 5.6.0 (46)
• opt into edge-to-edge and keep app bars, content, banner ads, navigation modes, and the IME clear of system insets
• make CI run release lint and bundle checks, correct the test ad unit ID, and keep Kover as an informational PR report without enforcing misleading overall or changed-file thresholds

Validation

• ./gradlew --no-daemon ktlintCheck koverXmlReportDebug lintRelease bundleRelease
  • 27 unit tests passed
  • lintRelease completed with 0 errors
  • bundleRelease completed with R8
  • Kover measured 111/1,160 lines (9.57%)
• APK metadata reports compile SDK 36, target SDK 36, version code 46, and version name 5.6.0
• API 35 emulator: cold start and UMP presentation
• API 37.1 emulator:
  • portrait and landscape
  • gesture and three-button navigation
  • search IME open/close and resize
  • navigation and system back
  • UMP accept/reject flows
  • test banner shown and hidden without system-bar or IME overlap
  • no AndroidRuntime crashes

Scope

This intentionally does not add play/foss flavors or replace the current UMP implementation. Those remain follow-up steps after establishing the common target SDK 36 baseline.

Defining filtered JVM coverage targets and separate instrumentation coverage remains a follow-up task.

The local release build used non-secret test ad placeholders and produced an unsigned AAB. Before a Play upload, verify the real ad configuration, release signing, version code availability, and Play pre-launch results.
