// Upload an Android App Bundle to a Google Play testing track.
//   storebound play upload [<app.aab>] [--track internal|alpha|beta|production] [--status completed|draft] [--version-code N] [--name text] [--not-sent-for-review] [--dry] [--yes] [--json]
// Default AAB: the newest in build/android (storebound play build), or with --version-code N the one with that
// versionCode. Package and versionCode are read from the bundle; the upload is refused when Play already has that
// versionCode (exit 1), and under the ship-step contract (--json / --result-file, docs/ship-step.md) it is exit 7
// "nothing to do" with the track and state that are there: never a second upload. Release notes: the "What's new" of
// every listing language. --dry is read-only (one throwaway edit: version codes and the track are read, the edit is
// deleted). A real run asks first (--yes in scripts). --track production sends the release to Google's review (a
// pipeline's update step); --status draft keeps it for the Console.
