ci: trigger native pipeline after ARC decommission

Empty commit to exercise the rewritten .hanzo/workflows/deploy.yml on
git.hanzo.ai. workflow_dispatch is accepted (HTTP 204) but creates no run on
this forge — every run is ev=push — so a real push is the only reliable
trigger. The previous failures were push events that predated the rewrite
reaching the mirror.
