/**
 * AppTweak metadata → minimal RawAppData adapter.
 *
 * The locGap text-judge consumes RawAppData; AppTweak gives us a slimmer
 * shape (title/subtitle/description/icon at most). Fields the judge prompt
 * doesn't critically rely on (developer, category, rating, screenshots) are
 * stubbed to safe defaults rather than fetched from a second endpoint.
 *
 * Returns null when metadata is null — that signals the underlying app has
 * NO localized listing in the requested language (AppTweak 422). The caller
 * (apptweak-loc-gap-runner) treats null as locGap=10 (max gap) without
 * spending an API call.
