feat(sms): add BlueBubbles iMessage delivery (Docker-OSX macOS VM pinned to worker-2) + ArgoCD app + dedicated longhorn-imessage-local SC — default longhorn SC can't schedule a 3-replica 200Gi volume (only worker-1 has 200Gi free at 100% over-provisioning) and Immediate binding would pin the qcow2 to the wrong node

- namespace: PodSecurity privileged, needed for /dev/kvm + privileged QEMU
- storageclass: 1 replica, strict-local, WaitForFirstConsumer
- deployment: nodeSelector workload=imessage + matching NoSchedule toleration,
  Recreate strategy (two QEMU procs on one qcow2 corrupts it), no readiness
  probe (guest install is interactive and takes many minutes)
- services: ClusterIP only; VNC is an unauthenticated console, reach it with
  port-forward, never an Ingress
- networkpolicy: default-deny, opt-in via sms-client=true on port 1234

+# iMessage delivery for the cluster.
+#
+# BlueBubbles' server is a macOS Electron app paired with an Objective-C helper
+# that hooks Messages.app private APIs — it cannot be containerised on Linux,
+# because containers share the host kernel and macOS needs XNU + Cocoa. The only
+# way to run it on Talos is a full macOS VM under QEMU/KVM (Docker-OSX), which
+# needs a privileged pod with /dev/kvm.
+#
+# Hence privileged PodSecurity: the cluster default from the Talos controlplane
+# is `enforce: baseline`, which forbids privileged containers and host devices.
+# Scope is limited to this namespace.
