fix(controller): set c->running in cluster_run so HA primary streams joblist/workerlist

Browse source 
cluster_start (which set c->running) is orphaned on the HA myapp_run path, so
the running flag was never set on HA nodes — check_controller() treated the
primary as shutting down and zeroed joblist/workerlist reply chunks. Own the
flag lifecycle in cluster_run, symmetric with the c->running=0 on shutdown.
