feat: migrate hosts-guard and shutdown-schedule-guard to guard-lib
Replaces the bespoke chattr/bind-mount/systemd-watcher implementations for
/etc/hosts and /etc/shutdown-schedule.conf with the new shared guard-lib
(~/guard-lib, guardctl), so screen-locker and steam-backlog-enforcer's new
block-gaming feature stop maintaining parallel copies of the same
tamper-resistance mechanism.

- pacman_wrapper.sh: pre/post hook fallbacks now call guard-lib's generic
  unlock-all/relock-all scripts (covers every registered guard instance,
  not just /etc/hosts)
- setup_midnight_shutdown.sh: installs/updates its guarded config via
  guardctl file-guard instead of hand-rolled chattr + systemd unit
  generation; the schedule ratchet logic (block-if-more-lenient) stays
  bespoke since guardctl's generic unlock can't represent it
- new hosts/guard/plugins/nsswitch-plugin.sh, resolved-plugin.sh

Also fixes, at user's request even though pre-existing: 3 shellcheck
SC2329 false positives in pacman_wrapper.sh (functions invoked indirectly
by name, not actually dead) and 1 SC2001 style warning (echo|sed VM-name
extraction replaced with parameter expansion, verified equivalent output).
