docs: Phase 1 review round — wake wording honesty, job-handle validity predicate, outbox/streams depth OQs

- C2: 'at-least-once wake delivery' collapsed to 'best-effort hints'
  (ADR-006 §1 + core-contract) — coalescing and the pg no-replay hole
  contradict per-commit wake promises; the guarantee table's row was
  already correct.
- W2: uniform job-handle validity predicate pinned (ADR-010 §2,
  core-contract, queues.md; verification-backlog row): processing
  state + unexpired deadline; D-12's missing-check not inherited.
- W1: outbox run_once worker semantics pinned in core-contract
  (pull op, ack/retry-on-curve, no heartbeat in delivery — honker
  parity, dual-execution window documented).
- W3: named-locks tx-seam posture stated (no lock_tx; acquisition is
  auto-commit; TTL discipline governs).
- C1 -> OQ-12: streams depth (key semantics w/ honker ground, event
  shape, ordering row, retention); method names pinned, depth open.
- New find -> OQ-13: the v1 TxHandle surface cannot express the
  transactional outbox enqueue (derived backing-queue name is
  reserved-prefix-rejected; honker's raw-Transaction seam unavailable);
  option set + decision rule sketched.
- README resolution order refreshed (OQ-06 resolved); ScheduleOpts +
  stream consumption-trigger lines added to core-contract.
