Skill: Android Release

• Use for APK/AAB packaging, signing, R8/ProGuard, versioning, and Play Console readiness.
• Never treat debug verification as enough for release-sensitive changes.
• Verify with ./gradlew :app:bundleRelease and ./gradlew :app:lintVitalRelease.
• Watch for keep rules, missing classes, signing mismatches, and versionCode/versionName drift.
• Call out release-only gaps explicitly.
