=== ZTunnel resource

The `ZTunnel` resource manages the L4 node proxy and is a cluster-wide resource. It deploys a DaemonSet that runs on all nodes in the cluster. You can specify the version using the `spec.version` field, as shown in the example below. Similar to the `Istio` resource, it also includes a `values` field that allows you to configure options available in the ztunnel helm chart.

The `metadata.name` field must be set to `default`, as enforced by a CRD validation rule that guarantees only one `ZTunnel` instance exists cluster-wide.
