feat: Add comprehensive diagnostics to cloud deployment workflow

Add detailed pod diagnostics to help troubleshoot agent startup issues:
- Pod status with wide output showing node placement
- Pod descriptions showing recent events and conditions
- Kubernetes events sorted by timestamp

This will help identify why pods are timing out despite:
- Image successfully loaded into minikube
- imagePullPolicy patched to Never
- Infrastructure deployed successfully
