TheOmenDen.StreamPulse.Scripting.Attributes.OnChatCommandAttributeMarks a method as a handler for a chat command — a message whose text begins with a prefix
(e.g. !) followed by a command word. The method must accept
(IScriptContext, ChatCommandContext); the context carries the parsed command word, the argument
text/list, and the sender's role flags. Which specific command (and minimum role) a handler responds to
is decided by the handler itself — a compiled graph bakes the authored command/prefix/min-role as a guard.
