A build whose agent never started is a distinct failure from one that lost a
connection mid-run, and a plain retry queues behind the same stuck pods. The
remediation clears pods that have already succeeded or failed - Ariadne's
existing scheduled cleanup - and only then rebuilds.
Mapping jenkins_agent_provisioning_failure to it keeps the one-classification-
one-action rule: a diagnosis asking for this action under any other
classification is still refused before anything runs.
