Implement TEN-WP-0011 security layer conformance
Engine/PIP declaration is now checkable (layer.yaml plus a Tooling-client
scan). Writes persist a decision record or the published fail-closed
stance, live-lookup freshness is published, events_for is tenant-scoped,
and mutation evidence drains to audit-core from a local outbox without
blocking the mutation.

Sender registration is requested as AUDIT-IN-0002. Boundary-contract
amendment is requested as NET-IN-0002.
