Two menu improvements.
Back everywhere: every list menu now ends with a "↩ Back" entry that
returns one level up — power, theme, power-profile, clipboard, files,
capture, not just Tools/System — so you no longer have to Esc out and
reopen to back up. A `back` helper + a shared `BACK` label keep it uniform;
matched exactly so it can't collide with clipboard/filename content. Esc
still quits instantly.
Snapshot fallback: btrfs-assistant 2.2 segfaults on 26.05 (libbtrfsutil
ABI), so `nomarchy-menu snapshot` now launches nomarchy-snapshots instead —
a keyboard-driven snapper browser/restore. snapper is root-only here and
rofi can't run as root under Wayland, so it runs in a terminal via sudo
(one password prompt) and uses fzf to pick: browse/diff (read-only),
restore files (undochange), or roll back (root config only), each behind a
typed-`yes` confirmation — safer than a one-click rofi rollback.
btrfs-assistant stays installed for when nixpkgs fixes it.
Verified: flake check clean; home generation builds and the menu passes
bash -n with all Back + snapshot wiring; nomarchy-snapshots passes
shellcheck (writeShellApplication) in a snapper-enabled system build.
Pending an on-machine check of the restore/rollback paths.
