Adds the VM/CDI storage tier approved by the PM (RWX for live-migration):
- platform/external-snapshotter (NEW, controllers pass): the cluster-singleton
snapshot.storage.k8s.io control plane (CRDs + snapshot-controller in
kube-system), pinned v8.2.0 (Kubernetes deps aligned to 1.31 since v8.1.0;
this cluster is k3s v1.31.5). These CRDs were absent — only snapshots.longhorn.io
and kubevirt.io snapshot CRDs existed.
- platform/longhorn/volumesnapshotclass.yaml (NEW, platform-config): the
driver.longhorn.io VolumeSnapshotClass (type: snap, in-cluster).
- platform/kubevirt/cdi-storageprofiles.yaml (NEW, platform-config): StorageProfile
longhorn -> cloneStrategy: snapshot; StorageProfile longhorn-vm -> snapshot clone
+ claimPropertySets RWX/Block. Non-degraded default virt class clears
CDIDefaultStorageClassDegraded.
- platform/longhorn/storageclasses.yaml: NEW longhorn-vm StorageClass —
migratable: "true" (Longhorn's KubeVirt-live-migration knob; RWX/Block-only on
1.7.3), is-default-virt-class (NOT the k8s default; longhorn stays RWO default).
- platform/kubevirt/kubevirt-cr.yaml: comment only — LiveMigration is GA on v1.9
(no feature gate); no cluster-wide evictionStrategy (would wedge RWO-disk drains);
live-migration stays per-VM opt-in on a longhorn-vm disk.

The 39Gi/node Longhorn data disks at 1:1 over-provisioning can't fit the media stack
(plex 20Gi replica failed: 'insufficient storage'). Volumes are thin-provisioned config-only,
so 200% lets the full catalog fit without a disk resize; physical fill risk is low. Also
right-sized plex config (20Gi was excessive for metadata). Prod-grade path: grow the data
disks (WS-STORAGE follow-up).
The un-suspend reconcile stalled: platform Kustomization Ready=False with
'StorageClass/longhorn ... .parameters.numberOfReplicas: expected string, got 3'.
StorageClass.parameters is map[string]string, but kustomize strips the quotes
around the bare "${LONGHORN_DEFAULT_REPLICA_COUNT}" placeholder, so Flux postBuild
substitution produced an unquoted numeric that server-side apply rejects as int.
Hardcode the quoted numeric literal "3" (kustomize preserves those, as "30" shows);
topology is locked at 3 nodes. The replica knob still drives the global default via
defaultSettings.defaultReplicaCount in the helmrelease (a Helm int value, unaffected).
