Proposed Changes:

Fix invoker to work when using dataclass with from_dict but dataclas is already given

Updated the component_invoker method to allow fully formed dataclass objects to pass through. Otherwise we silently remove the parameter value.

Originally found by @bilgeyucel when creating an tool using Agent + ComponentTool and calling

agent_tool.invoke(messages=[ChatMessage.from_user("Tell me the latest news about gpus")])

How did you test it?
