refactor(jobs): type the producer face by the record declaration, tidy review residue

- `JobStart` is a union discriminated by `record`: `RecordingJobStart.run`
  receives `RecordingJob` (with `append`), `PlainJobStart.run` receives the
  plain `RunningJob`, and the registry builds the plain face without the
  method, so the former warn-and-drop path is unrepresentable.
- Remove the duplicated JSDoc opener in the registry seam and correct the
  job-list slot comment (order 20 sits before the subagent catalog's 30).
- Restore the `cordis-tool-round` session fixture whose only change was a
  re-recorded `createdAt`.
- Update the 2026-08-08 job-display note's stale service-disposal and slot
  ordering facts; archive the superseded 2026-08-25 unified-task-list note
  and point its remaining inbound links at the archived snapshot.
