Subject: [PATCH 2/2] fix: Restrict replicaset namespace relationship to cut
 CPU/event volume

Excludes scaled-to-zero ReplicaSets (podsDesired=0) from the NRI-based
rule, which account for over half of matched K8sReplicasetSample events
in sampled data - these are historical rollout artifacts with no live
pods and don't need a continuously-refreshed namespace edge.

Also fixes the OTel rule's source resolver from lookupGuid to buildGuid
to match the Deployment/DaemonSet/StatefulSet sibling rules, removing an
unnecessary candidate-search lookup on every matched event.
