[BUG] Claude Code 2.1.121 Ink TUI incompatible with GNOME Terminal on Ubuntu 24.04

Preflight Checklist

• [x] This is a single bug report (please file separate reports for different bugs)

What's Wrong?

In interactive mode (claude without --bare), Claude Code starts but does not respond to user input. The TUI built with Ink (React for terminal) fails to render properly in GNOME Terminal, causing the entire session to hang when user types a message.

claude --bare mode works perfectly — this confirms the issue is specific to the Ink-based TUI.

What Should Happen?

Claude Code should render its TUI and respond to user input normally.
