[bug\_fix] Node NotReady

Run \`kubectl describe node \` to read the Conditions. If \`DiskPressure\` or \`MemoryPressure\` is True, free disk or evict pods. If \`KubeletNotReady\`, SSH to the node and check \`journalctl -u kubelet\`. Restart kubelet if it is stuck, or clear \`/var/lib/kubelet\` lock files if the node was improperly shut down.

Journey Context:
Many Pods are stuck \`Pending\` and \`kubectl get nodes\` shows one node \`NotReady\`. \`kubectl describe node\` reports \`Ready False\` with \`KubeletNotReady\` and \`DiskPressure True\`. You SSH to the node and \`df -h\` shows \`/var/lib/containerd\` at 99%. Containerd cannot create new container layers, so the kubelet stops scheduling and marks the node NotReady. You prune unused images with \`crictl rmi --prune\` and clean old logs, disk pressure clears, and after the kubelet updates its status the node returns to Ready. If the condition was \`PIDPressure\`, you identify a runaway process and restart it.
