Checkpoint one completed Evaluation case

POST/v1/evaluations/runs/{runId}/checkpoints

Requires the current reserved Evaluation dispatch credential and a matching unexpired resource lease. Identical replay is idempotent; accepted results are immutable. Ordinary API and Agent callers cannot create worker checkpoints.
