Fix Enter during IME composition sending the message

[kote2kote]

Problem

When typing with an IME (Japanese, Chinese, Korean input methods), pressing Enter to confirm a text conversion is interpreted as a send action. This makes the chat input nearly unusable for CJK users: every conversion confirmation sends a half-written message.

Fix

Guard the onKeyDown handlers with the standard IME check:

if (e.nativeEvent.isComposing || e.keyCode === 229) return;

keyCode === 229 covers browsers (notably Safari) that fire the confirming keydown without isComposing set.

Applied to the three text inputs in ChatInterface.tsx that submit on Enter:

• the main chat message input
• the chat list rename input
• the chat title edit input

Testing

• With a Japanese IME: type text, press Enter to confirm the conversion → message is not sent; press Enter again → message sends.
• Without an IME: Enter sends, Shift+Enter inserts a newline, slash-command picker Enter/Tab/arrow behavior unchanged (the guard returns before those branches only during active composition).
• tsc --noEmit passes in packages/workshop-frontend.

After opening this I noticed #31 addresses the same IME composition bug in the chat composer and was submitted first — apologies for the overlap.

For the maintainers, the differences in this PR:

• It includes the keyCode === 229 fallback for the Safari/WebKit event-ordering case raised in this comment on #31 (WebKit bug 165004), where compositionend can fire before the confirming Enter keydown so isComposing is already false.
• It applies the same guard to two other Enter-submitting inputs with the same bug: the chat list rename input and the chat title edit input.

Happy to defer to #31 and close this one if you'd prefer to land that first — either way, whichever base you pick, the 229 fallback and the two extra inputs are probably worth including. Your call.
