jenkins d1e8cda5ed hermes: make supervisor terminal emissions idempotent across ticks
Fix reviewer BLOCK: the stateless poll loop re-planned every terminal card each
tick, so SHIP and the two cycle-limit escalations - whose source cards stay in
the done state - re-fired their comment/block on every pass (~2880/day/chain).

- Add a persistent emission Ledger (/opt/data/supervisor/emitted.json): SHIP and
  escalate perform their action only when the (action, target) key is absent,
  then record it, so each fires at most once and survives a pod restart. Spawns
  remain self-limiting via the existing dedup scan.
- Cycle-limit escalations now target the SOURCE review/repair card (not the impl
  root), so the card also leaves the done state and is skipped next tick even if
  block_task round-trips imperfectly.
- Harden the _spawn TypeError fallback: re-run the dedup scan before retrying so
  a post-insert TypeError can never double-insert.
- Add across-ticks idempotency tests (10x supervise_once -> exactly one
  comment/flag/block) plus ledger persistence/corruption and spawn-guard tests.

Both modules stay 100% line+branch, <500 LOC. Stacks on the merge train
(base 5f27e50c).
