Package the reviewed keycape-services JWT mount, secrets-engine-openbao role
and secrets-engine-login-self policy as CCR-2026-0038 and teach the delegated
applier a narrow service-jwt-login request type: fixed mount, generated
login-self policy, allow-listed role/config keys, bounded TTL/uses, refusal on
a foreign mount type and a value-free readback compare. The policy now denies
the client-secret data/metadata paths explicitly (MASON-WP-0009 invariant ii).
Proposed only; founder approval and delegated apply pending.
