Every module imports cleanup.nix (also exported as homeManagerModules.cleanup), which - puts steam-frame-nix-cleanup (install.sh cleanup) on PATH; - runs `cleanup --orphans --quiet` after linkGeneration on every switch, keeping what the configuration still uses (steamFrame.cleanup.keep, set by the modules: debugger while steamvrDebugger is on, the Firefox desktop profile's user.js while its fix applies); in a dry run it runs with --dry-run; - runs `cleanup --all` instead when Home Manager's `uninstall = true;` is set (the manual uninstall route); - removes links of older versions at paths Home Manager is about to own before checkLinkTargets (steamFrame.cleanup.migrateLinks), which would count as collisions otherwise. install.sh cleanup gains --quiet (only actions, deferrals and warnings; the header only when something is printed). The Jellyfin module's own removal of the old shim copy goes: cleanup does it.
