Single Node Openshift (Sno) Test Compatibility	✅ Passed	The diff adds no Ginkgo test declarations. It only enables HostPath group snapshots; existing suites use unconstrained StatefulSet replicas and do not require multiple nodes.

Enable CSIVolumeGroupSnapshot in the CSI snapshotter sidecar.

When group snapshot tests use InitHostPathCSIDriver, the csi-snapshotter:v8.6.0 manifest lacks --feature-gates=CSIVolumeGroupSnapshot=true. The v8.6.0 sidecar requires this flag. Add it through PatchCSIOptions or the rendered manifest.
