The second queue parser shadowed handler-compatible flags (--head,
cancel --task, schedule --drain), so enqueue/cancel/schedule failed
at runtime and queue_items stayed empty. Keep the first registration
and add regression coverage for parser flags, roundtrip, and schedule.
Add whole-doc and row projection with hash CAS, real enqueue→claim→
fake-deploy→SQLite receipt chain, Darwin lsof cwd visibility, and
black-box tests. PI image compose remains deferred.
Consolidate approved policies and add local lease, document CAS, commit, candidate and environment gates. Preserve conservative recovery and cleanup limits.
