Backend serves a staged APK so co-users self-serve the latest build:
- GET /api/apk streams APK_PATH (default /data/novasonic.apk) with the
android package content-type + attachment disposition; 404 if absent.
- GET /api/apk/info reports availability, size, mtime, and an optional
version from /data/novasonic.version.txt.
- Settings gets a "🤖 Android App" section that appears only when an APK is
present and shows version/size/date.
Maintainer updates the APK with:
docker cp app-release.apk novasonic-backend:/data/novasonic.apk
Android source is already tracked; only build artifacts stay out of git.
