Fixes #2272

Risks

Low:

• This change only affects the onKeyDown event handling logic in chat.tsx.
• It has been confirmed to work correctly even in non-IME environments.

Background

What does this PR do?

This PR resolves an issue where using an Input Method Editor (IME) for languages like Korean, Japanese, or Chinese would cause multiple messages to be sent when pressing Enter. Now, pressing Enter after input will only send the message once.

What kind of change is this?

Bug fix:

• Modified the onKeyDown event handling logic in chat.tsx to properly handle IME input and ensure a single message is sent.

Documentation changes needed?

My changes do not require a change to the project documentation.

Testing

Where should a reviewer start?

• Review the onKeyDown event handling logic in the chat.tsx file.

Detailed testing steps

1. Launch the application.
2. Enable an IME (e.g., Korean).
3. Type text into the chat input field.
4. Press Enter after typing:
   • Verify: The message is sent only once.
