What's Wrong?

## Bug description
Claude Code interactive mode does not accept keyboard input when running
over SSH. The TUI launches and displays correctly, but the cursor does not
move and no keystrokes are registered. Non-interactive mode (claude -p)
works fine.

## Regression

• Works: v2.1.29
• Broken: v2.1.31
• Rolling back to 2.1.29 via symlink resolves the issue.

## Environment

• Local OS: macOS
• Remote OS: Rocky Linux 8.10 (RHEL 8 based)
• Node.js version: v20.19.5
• Terminal: Terminal.app

## Steps to reproduce

1. SSH into a remote Linux host
2. Run claude (v2.1.31)
3. Claude Code TUI launches but input is completely unresponsive
4. Downgrading to v2.1.29 restores normal behavior

What Should Happen?

keyboard input to claude should work normally.
