Adds the full Android source tree with unit tests, fastlane store metadata and the Gradle wrapper. The archive shipped without gradle-wrapper.jar, so the official Gradle 9.7.1 wrapper jar is included to make ./gradlew work from a fresh clone. .gitignore now also excludes build output and keystores. README gains build instructions and an updated structure tree. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_015g6ECVSKcBG8CJPrqC3G5o
