The deployed cluster has TWO default StorageClasses — k3s's built-in local-path
AND longhorn — which is ambiguous for PVCs without an explicit class. Longhorn
(ADR-0003) is the cluster storage, so add local-storage to k3s --disable. Effective
on fresh installs (the k3s install task is idempotent → no restart of the running
cluster); the running dev cluster keeps both defaults harmlessly (all platform PVCs
pin storageClassName: longhorn). Rebuilds get a single default.
