Subject: [PATCH] Add standalone Tor deployment

ClusterIP SOCKS5 proxy on 9050 for pod outbound via Tor, plus hidden
service for monerod (P2P 18080 + restricted RPC 18089). PVC holds
/var/lib/tor so the onion hostname persists across restarts.

+# Tor — standalone cluster Tor daemon
+#
+# Two jobs:
+#   1. Hidden services for internal cluster services (start: monerod).
+#   2. SOCKS5 proxy on ClusterIP:9050 for pods that want outbound via Tor.
+#
+# PVC holds /var/lib/tor — hidden service keys. Losing this = new .onion.
+# Uses local-path (fine: keys are tiny; node loss means regenerate onion,
+# not end-of-world). Switch to nas-nfs later if that matters.
+#
+# After apply, read the onion:
+#   kubectl exec -n default deploy/tor -- cat /var/lib/tor/monerod/hostname
+#
+# Deploy:
+#   kubectl apply -f tor.yaml
