Playbook for taking any Heluca app from repo to Google Play, learned from
shipping Dade to internal testing: one-time publisher account + upload keystore
setup, per-app checklist (signing via -Pandroid.injected.signing.*, AAB,
versionCode encoding, native symbols), internal-testing flow, gotchas, and
production promotion. Bakes in Heluca conventions and documents where Dade
deliberately diverges (custom signingConfig, UPLOAD_* secret names, :latest pin)
so the next app can follow the template instead.
