Drop omarchy-limine package; settings now ships limine configs

Pairs with omarchy-pkgs' fold of omarchy-limine into omarchy-settings.

Changes:
- EARLY_BOOTSTRAP_PACKAGES in phases_impl.py drops omarchy-limine.
  The limine configs it shipped (mkinitcpio hooks, entry-tool drop-ins,
  snapper template, default/limine/, default/snapper/) now come with
  omarchy-settings, which is already in the early bootstrap.
- builder/build-iso.sh's offline-mirror seed list and post-mirror filter
  no longer reference omarchy-limine.
- builder/build-omarchy-packages.sh's build queue drops omarchy-limine.
- Test manifests (fresh-4.json, fresh-4-semantic.json) no longer expect
  omarchy-limine in the installed-packages list. The /etc/pacman.d/hooks/
  99-omarchy-limine.hook entry stays — that hook file is generated by the
  orchestrator regardless, and the filename is descriptive, not tied to
  the package name.
