Republish bibata-cursor-theme to [breadway] (AUR-only upstream)

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.

+# [breadway] repo so the ISO build can pull it via pacman (same pattern as
+# zen-browser-bin and calamares). Prebuilt release tarball — no build step.
