SboxSuperuser/Engine/Compatibility/ProbeChat.cs
A small compatibility helper that listens for a specific chat command (/superuser-probe). When seen from a player it suppresses the public chat, logs the event, and sends a host-only RPC back to the sender to display a private chat message and log receipt.
