Issue Checklist

• I understand that issues are for reporting problems and requesting features, not for off-topic comments, and I will provide as much detail as possible to help resolve the issue.
• I have checked the pinned issues and searched through the existing open issues and closed issues and did not find a similar suggestion.
• I have provided a short and descriptive title so that developers can quickly understand the issue when browsing the issue list, rather than vague titles like "A suggestion" or "Stuck."
• The latest version of Cherry Studio does not include the feature I am suggesting.

Platform

Version

Is your feature request related to an existing issue?

现在如果在生成中，按回车会提示等待回复结束。如果要打断得点击暂停，然后发送。能不能支持回车自动打断

Desired Solution

优化“回复中”回车操作：

第一次回车 → 提示“回复未完成”
第二次回车 → 自动暂停当前回复并发送新消息
