Insert a new line with Enter key instead of sending a message

[tmokmss]

I'd like to have an option to insert a new line with Enter key instead of sending a message. In CJK languages enter key is used to confirm the input and the current key binding very often leads to an incomplete message mistakenly sent to claude, which is annoying.

Currently we can only add new line with shift+enter by /terminal-setup command, but it does not support enter to add new line.

Just realized I created a duplicate of your issue here: #2335.

I really want this option!
It’s super inconvenient for speakers of languages like Japanese, where we use Enter a lot when writing, to have it submit with Enter.
