Post plugin verb invocation result

Called by the daemon after executing a polled plugin verb invocation. Ordinary local-bridge results keep the existing resume behavior. `rensei.verify.run` is a strict runtime-JWT-only branch (maximum 2 MiB) requiring `X-Rensei-Claim-Acknowledgement-Receipt-Sha256`; it settles canonical result bytes and returns Donmai acknowledgement authority but never resumes the workflow. Positive continuation occurs only at acknowledgement confirmation. Duplicate settlements are replay-safe and conflict on changed stable bytes.
