What's Wrong?

Mouse scrolling and arrow key navigation stopped working in Claude Code 2.1.239. This prevents scrolling through session history and using arrow keys for command-line editing.

What Should Happen?

Expected behavior:

• Mouse scroll wheel scrolls through session history
• Arrow keys allow navigation within the terminal

Actual behavior:

• Mouse scroll does nothing
• Arrow keys do nothing (Page Up/Page Down work as workaround)
