+feat(vis): show LAN URLs when binding to 0.0.0.0 for remote control
+
+When vis-server binds to 0.0.0.0 or :: (all interfaces), the startup
+banner and CLI output now display the actual LAN IP addresses that
+other devices on the same network can use to connect. This enables
+lan-range remote control from phones, tablets, or other machines.
