* agent: release JobTerminate handler when job ends before registration JobRequest registered the job's JobTerminate handler after AssignJob returned, so an ended UpdateJobStatus or worker disconnect handled in between deregistered nothing and the handler leaked. AssignJob also sent the assignment before recording the job as running, so an immediate ended update was dropped. Record the job before sending the assignment, and after registering the handler recheck under h.mu that the job is still running and its worker still registered, deregistering otherwise. Fixes #4901 * replace utils.CloneProto with proto.CloneOf * agent: wait on worker readiness and poll for released handlers in test
