Production-launcher / audible-playback packaging repair.
Primary download is now the non-debuggable release variant, not the dogfood/debug harness APK. The release launcher is dev.androidjtools.shell.AndroidDjToolsActivity and routes into the real MediaStore + Media3/ExoPlayer playback path. The debug harness is absent from the release APK.
Temporary gate override: the APK-producing Android CI job and production-launcher verification passed on commit 131b33e. API-35 E2E was explicitly overridden per operator instruction; the screenshot job was still running at publication. See release-provenance.json.
Signing note: this is a release build but currently uses the project development signing profile for sideload installation, not Play Store signing.
