Give each feature a bolded name with a short description, add large-library
and offline-mode points, and bring the store description's order and content
in line with the README.
Drop the "API" from the server compatibility wording, and lowercase the brand
in the title, description, old changelog and the app name to match the logo.
Bump versionCode to 13 and versionName to 3.0.0. The Flutter app ended at
2.0.0-alpha.3+12 (versionCode 12), so 13 keeps the eventual com.subtracks
release an in-place upgrade.
Metadata was still inherited from the Flutter app:
- add the changelog for versionCode 13
- rewrite the descriptions for the native app
- replace the Flutter phone screenshots with native renders, and mute the
screenshot fixture palette so the placeholder artwork reads as covers
