What this controller does (precisely)

Continuously:
	1.	Watches Nodes
	2.	If a Node is NotReady longer than a configurable timeout
	3.	Finds Pods on that node
	4.	Deletes only Pods that:
	•	are owned by Deployments or StatefulSets
	•	are NOT DaemonSets
	5.	Lets Kubernetes reschedule them on healthy nodes

It does not:
	•	Drain nodes
	•	Touch DaemonSets
	•	Touch mirror/static pods
	•	Interfere with kube-system (unless you allow it)



NOT_READY_GRACE_SECONDS=600     # default: 10 minutes
