chore: record cumulative review batches 34-36 + state

Cumulative code review for batches 34-36 (AZ-507, AZ-323, AZ-324,
AZ-306, AZ-322) per implement skill Step 14.5 K=3 cadence.

Verdict: PASS_WITH_WARNINGS — 0 Critical / 0 High / 0 Medium / 3 Low
(all Maintainability). Previous review's Medium F1 (doc-vs-lint) is
RESOLVED by AZ-507. Carryover-Low findings tracked:

- F1: manifest_verifier imports private _aggregate_tile_hash from
  manifest_builder; promote to public or extract to a shared module
  (1-pt follow-up PBI).
- F2: AZ-508 task spec stale — c6 already consolidated within-component,
  c7 has 2 active copies (+ a new thermal_publisher copy not in spec).
- F3: consumer-side Protocol cut pattern still un-documented in
  architecture.md; pattern now 9+ instances and is the established
  cross-component contract surface.

State updated: last_cumulative_review = batches_34-36; sub_step =
parse-tasks; batch 37 (AZ-325 C10 CacheProvisioner solo, 3pt) is next.
