Hide unfinished games from production builds

A release listed all eleven games with nine of them marked "Coming
soon", so most of the menu was a dead end for anyone installing from the
production channel. Production now lists only what can be played; dev
builds still show everything, which is where seeing the roadmap is
useful.

The menu reads the installed APK's own version name, so this follows the
build rather than the update channel selected for the future — a dev
build shows the full list even if its owner has switched back to
production for updates.

CatalogTest pins both views, including that filtering never empties a
category and strands its heading.
