Bibata is the chosen BOS default cursor but is AUR-only, so mirror the
prebuilt -bin package into the [breadway] repo the same way calamares and
zen-browser-bin are. The workflow clones the triggering branch (not the
default branch) so it can build from iso-boot-fix, and uses the scoped
REGISTRY_TOKEN for publishing.
Calamares isn't in Arch's official repos, so BOS vendors the PKGBUILD and
publishes a built package to the [breadway] repo. All its deps are official
(kpmcore, qt6-*, yaml-cpp). Also drop the nonexistent calamares-qt6 from the
package list (calamares 3.4.x is already Qt6).
Mirrors the build/distribution pattern used by the bread project:
- bakery.toml describes bos-settings as a bakery-managed package
- packaging/arch/PKGBUILD builds and installs the binary via cargo
- packaging/arch/bos-settings.desktop for app launchers
- LICENSE (MIT) required by PKGBUILD
