An option in the text box for chat to 'expand' so that ENTER key does not submit but acts as enter key. Along with that, bullet points.

Currently have to always SHIFT ENTER to avoid accidentally sending when I am writing longer prompts and want to section or bullet areas.

从 /chat 入口开始，跟踪文本框的键盘处理和提交行为。明确展开选项和项目符号应如何工作，然后验证展开后的文本可以接受换行而不会意外提交，同时现有的发送行为仍然可用。
