Description
In the following example, the tool call event and the tool call output event are triggered simultaneously,and I believe it's more reasonable to separate them.

For event.item.type in "tool_call_item" and "tool_call_output_item", they are triggered simultaneously, and I believe it's more reasonable to separate them.
