Confirm Donmai terminal lease acknowledgement and authorize continuation

Runtime-JWT-only confirmation for a settled `rensei.verify.run` result. Requires `X-Rensei-Confirmation-Attempt: 1|2`, exact retained settlement/result-response digests, and a canonical Donmai acknowledgement outcome. Applied outcomes may retain `release-pending` with provider release incomplete or observe `released`; permitted rejection outcomes authorize only the action-failure edge. This is the sole positive continuation authority; the result endpoint itself always reports `resumed: 0` for first settlement.
