[YellowDusk04]

优化工具调用响应校验逻辑

仅校验工具调用后连续的工具响应结果，遇到非工具消息立即终止遍历；
原逻辑无此判断，会遍历所有后续消息。

optimize tool call response validation logic

Only check consecutive tool responses after the tool call and stop traversing when a non-tool message is encountered;
The original logic traversed all subsequent messages without this judgment,.
