A store's own engine can take that store away. What was missing was a way to take the framework off a machine without having to remember what is on it: uninstall.sh finds every store home under both known roots, has each store's own engine purge what it installed, and then removes the store, its launcher, its Ports entry and the engine files. It delegates the removing rather than repeating it, because only the engine's state.json knows which ROMs, playlists, thumbnails or gamelist entries were a store's. If an engine cannot finish — RetroArch running, a ROMs root unmounted — the run stops there instead of deleting the engine that knew what it had installed. POSIX sh, not bash, so `curl … | sh` works on a machine whose /bin/sh is dash; checked with dash. `prune_empty_dirs` moves here for the same reason the delete guard `within()` did: both engines need it, and both need it to be careful. It removes only directories that are actually empty, and only inside the subtree the store owns, so one surprise file is enough to keep a directory.
