Adds a `globalManager` block in values.yaml (default `enabled: false`) and a templated `longhorn-global-manager` Deployment. When enabled, the DaemonSet is launched with `--node-local-only`, and the cluster-wide controllers (KubernetesPVController and KubernetesPodController) run in this Deployment as a leader-elected singleton instead of in every DaemonSet pod. Default-off so existing operators see no behavioral change on upgrade. Multiple replicas are supported with hostname anti-affinity for hot standby, and a livenessProbe hits the global manager's /v1/healthz endpoint (port 9505), which represents process liveness regardless of leader status so standby replicas stay Ready.
