Add ops-warden INTENT as operational access steward for NetKingdom
security (route credential lanes, align docs, issue SSH certs only).
Refresh SCOPE for stewardship scope, persist INTENT↔SCOPE gap assessment,
and open WARDEN-WP-0006 for routing runbooks and platform alignment.
Document OpenBao as the platform production secrets service while keeping
the vault-compatible warden.yaml config shape. Update OpsWardenConfig,
SCOPE, and CertCommandInterface cross-references.
Update SCOPE and README to reflect the shipped warden CLI, fill agent
rules for stack/architecture/boundary, archive finished workplans
0001–0003, and register WP-0004 in State Hub.
