ci: canonical pair — hanzo.yml + forge caller

github.com has no runner for hanzo-build-linux-amd64, so a caller under
.github/workflows is a gate that can never be scheduled. This is the ~7-line
caller on the plane that can (git.hanzo.ai git-runner fleet), pinned @v1.

+# macOS/Android-image lanes, not a merge gate — claiming them here would be
+# claiming a coverage this runner cannot produce. What does run is the part
+# that is plain Node: the device drivers' state machines, the matcher and
