The previous version made the local build the only path. Convention is
the opposite: omarchy-iso-make pulls released omarchy* packages from
the omacom-pkgs.org mirror by default, and only builds from local
checkouts when explicitly asked via --local-source.
- bin/omarchy-iso-make: only mount /omarchy-installer + /omarchy-pkgs
when --local-source is set. Default has neither mount.
- builder/build-iso.sh: skip build-omarchy-packages.sh when no local
source. Don't filter the omarchy* names out of the pacman -Syw list
in network mode (so they get downloaded from the mirror). With
--local-source, the four package names are stripped after assembly
so we don't re-fetch what we just built.
- For the package-list source: with /omarchy-installer mounted, read
omarchy-base.packages from the checkout. Without it, briefly pull
the published omarchy package, extract the .packages files from it
to /tmp, and use those.
