[bug] the operator fails to parse checkpoint metadata on containerd based clusters #95

@slashexx

Description

@slashexx

The operator has hardcoded io.kubernetes.cri-o.Labels to extract pod/namespace/container metadata from dump, but containerd uses a different annotation format (io.kubernetes.cri.*)

Faced this error while the operator was trying to checkpoint in a locally setup kind cluster (which uses containerd out of the box)

2026-03-24T12:59:58Z	ERROR	runGarbageCollector():getCheckpointArchiveInformation()	{"error": "failed to read \"io.kubernetes.cri-o.Labels\": unexpected end of JSON input"}

Will gladly take this up post triage :)
