--update reuses the options an install was made with (saved to install.conf in the work dir) and
builds nothing when the Frame already has the newest release and Retro Rewind pack; --check only
reports. The installed release is stamped as .release-tag beside the game on the Frame.
An install built on the Frame itself (--frame local) also gets a systemd user service the game's
new Updates tab starts: the update runs in the background at low priority, writes each step and
the build percentage to a status file the tab shows, and reopens the game at the end if it was
closed. Progress does not go through Steam notifications: on the Frame, Steam receives them from
steam_notif_daemon but does not display them.
