With the cleaner dep graph, omarchy-installer no longer transitively
pulls omarchy + omarchy-settings + omarchy-limine. Pacstrap both
explicitly so /etc/skel (via omarchy -> omarchy-settings) is populated
before archinstall creates the user.
archinstall creates the user AFTER pacstrap. If omarchy-settings (which
ships /etc/skel/.config/**) isn't pacstrap'd, the user is created with
an empty skel and never gets the Omarchy default configs in their HOME.
Add omarchy-installer to the configurator's archinstall package list
(its depends pull omarchy + omarchy-settings + omarchy-limine), so all
the package files are in place before the user is created.
install_omarchy no longer needs the explicit 'pacman -S omarchy-installer'
step; it just runs 'omarchy-install' which is already at /usr/bin/.
