SboxSuperuser/Engine/CommandDiscovery/HandlerSignature9.cs
A small internal class that validates a method signature for command handlers with nine generic parameters. It checks the method's return type and attempts to create a closed delegate Func<T1,...,T9,CommandResult> or Func<T1,...,T9,Task<CommandResult>> to ensure the method can be bound without invoking it.
