Add a Standard Supplement to SCS-0217 (Cluster Hardening) documenting the K3s-specific implementation notes verified on a 3-node bare-metal K3s cluster (embedded etcd/dqlite, built-in NetworkPolicy controller, Pod Security baseline, storage-class default, node topology labels).

Reference: 3-node bare-metal K3s cluster (one master, two workers) with Ceph RBD storage, HAProxy ingress and Flannel CNI.

Note: AI-generated content, kept in draft until fully reviewed/tested.

consistently name the reference implementation hosts
(k3s-master-01/k3s-worker-01/k3s-worker-02).
