[bug\_fix] Pod stuck in ContainerCreating due to CNI not ready

Check \`kubectl describe pod\` events for CNI errors, ensure CNI pods \(e.g. calico-node, cilium, aws-node\) are Running, verify node has a valid CNI config in \`/etc/cni/net.d\`, and restart the CNI daemon pod if its socket/state is stale.

Journey Context:
A pod remains ContainerCreating for minutes. \`kubectl describe pod\` shows events 'Failed to create pod sandbox: rpc error: code = Unknown desc = failed to setup network for sandbox ...: plugin type="calico" failed \(add\): error getting ClusterInformation'. The calico-node pod on that worker is CrashLoopBackOff because it cannot reach the Kubernetes API due to a network partition. Restarting calico-node and verifying the CNI config in \`/etc/cni/net.d/10-calico.conflist\` exists allows sandbox creation to proceed.
