+### Resource Cleanup
+ktunnel now automatically tracks and cleans up resources (deployments and services) when the process exits. This ensures no orphaned resources are left in your cluster, even after unexpected shutdowns.

+- A 30-second timeout ensures cleanup doesn't hang indefinitely
+- Use the `-v` flag for verbose logging to see cleanup operations
