Subject: [PATCH] ci: add Android CI/CD workflow

.github/workflows/android-ci.yml:
- Triggers on push to main and pull requests
- Ubuntu-latest runner with Java 17 (Temurin)
- Gradle cache via gradle/actions/setup-gradle
- Jobs: assembleDebug build + unit tests (./gradlew test)
- Uploads debug APK as workflow artifact (14-day retention)

Closes #14
