Subject: [PATCH] ci: trigger backend pack on UI merge
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After build-publish uploads the UI tarball to COS, dispatch a
repository_dispatch event (ui-built) to gpustack/gpustack so the
backend repack picks up the new UI.

Skipped for tag pushes — release tags drive the backend pack via
its own tag trigger. Requires a DISPATCH_PAT secret with
actions:write on gpustack/gpustack.
