* feat(nushell): add trash command using the home trash can On a tmpfs root with persistent dirs bind-mounted in, `rm --trash` scatters items into per-mount .Trash-$uid dirs that file managers never show, and gio refuses to trash on those internal mounts. Add a `trash` command implementing the freedesktop trash spec 'failsafe' mode: items are moved to ~/.local/share/Trash with spec-compliant .trashinfo entries, so Thunar can list and restore them. Also preserve ~/.local/share/Trash on idols-ai so the trash survives reboots. * feat(nixos): manage scattered trash dirs with trash-cli retention timer Replace the hand-written nushell trash command with the established trash-cli tooling. On a tmpfs root with persistent dirs bind-mounted in, the trash crate (nushell rm --trash) scatters items into per-mount .Trash-$uid dirs that file managers never show and nothing cleans up. - add trash-cli to system packages: trash-list scans/trash-restore handles every mount point's trash dir - daily systemd timer runs 'trash-empty 30 -f', purging items older than 30 days across the home trash and all mount points - drop the hand-written trash.nu module - note in preservation.nix: do NOT persist ~/.local/share/Trash; a bind-mounted trash dir breaks the trash crate's home-topdir match for files straight under $HOME (it would try /.Trash-$uid, EACCES) * fix(nixos): order trash-empty after preservation.target The scattered .Trash-$uid dirs live inside the preservation bind mounts, which use DefaultDependencies=no and are therefore NOT ordered after local-fs.target. Add preservation.target to After= so trash-empty only runs once all those mounts are up.

# crate (nushell `rm --trash`, GUI file managers) scatters items into

# trash-list # view items in all trash dirs

|
# trash-restore <file> # restore an item
|
|
# trash-rm <file> # remove a single item from the trash
|
