README and packaging/ now describe bakery (CI + ISO bake) as canonical
instead of the old pacman package.yml flow. Pin bread-theme and
bread-utils to bread-ecosystem v0.7.1; rev-pin bread-screenshots because
that crate is not in the tag. Update the essential-keybinds guide to
match the BOS skel (nautilus, lock, breadshot).
Adds the release/CI machinery bos-settings already has in its own repo:
Forgejo package.yml (tag -> build -> publish to [breadway]) and
mirror.yml (Forgejo -> GitHub). PKGBUILD updated for the flattened
layout and dropped -p breadhelp now that this isn't a workspace member.
