RBAC: the built-in view ClusterRole (which never includes Secrets, so
Vault-managed material stays structurally invisible) plus a read-only
extra for nodes, namespaces, PVs, storage classes, CRDs, Flux resources
and metrics, bound to the chat service account. Tooling: a cluster-read
plugin registers a GET-only cluster_read tool against the in-cluster
API using the pod's projected token - secrets paths refused in the
handler as well, malformed segments rejected, responses bounded and
stripped of managedFields noise. Classified read_files/low in the HUX
capability map. RBAC applies on push; the tool activates when the pods
next roll (bundled with the round-3 voice build).
