A gpus entry now names a raw resource, a held GPUClaim or a
claimTemplate that orders a claim for as long as the VM runs. The
chart renders references only as the claim-reference label and the
claims annotation on the VMI template; the GPU webhook resolves them
at VMI creation and writes the gpus entries itself, so a list holds
raw names or references, never both.
Where gpu-operator does not serve GPUs to VMs no webhook would resolve
a reference and the VM would boot without its GPUs, so the platform
publishes the switch in _cluster and the chart refuses references
without it.
