Viktor Barzin bcf22640b2 keel: enroll 11 more namespaces (operators + critical infra)
Per user decision, removed authentik, kyverno, metallb-system,
external-secrets, proxmox-csi, nfs-csi, vpa, sealed-secrets,
infra-maintenance from the policy-level exclude list, and added
keel.sh/enrolled=true to aiostreams (alive — 1/1 Running, despite
being earlier flagged as scaled-to-0) and woodpecker.

Net cluster coverage: 197/227 workloads on safe-force (86%), up from
170/227 (74%). All 197 are paired with match-tag=true (digest-only).

Remaining 7 namespaces in Kyverno exclude list (irreducible):
- keel (self-update)
- calico-system + tigera-operator (operator-managed Installation CR)
- cnpg-system + dbaas (state-coupled)
- nvidia (chart-pinned at 570.195.03 per code-8vr0 until NVIDIA ships
  ubuntu26.04 driver images)
- kube-system (k8s built-ins)

Files:
- stacks/kyverno/modules/kyverno/keel-annotations.tf — exclude list
  trimmed from 16 → 7
- stacks/authentik, kyverno, proxmox-csi, nfs-csi, vpa, sealed-secrets,
  servarr/aiostreams, metallb (creates ns "metallb-system"), woodpecker —
  added keel.sh/enrolled=true label on kubernetes_namespace resource
- infra-maintenance was in the policy exclude but the namespace doesn't
  actually exist in the cluster; the removal is a no-op there

Applied via kubectl patch on the live ClusterPolicy + kubectl label on
namespaces because the kubernetes provider v3.1.0 panics on Kyverno
ClusterPolicy refresh — TF source has the desired state for next clean
apply on a fixed provider.
