[Bug] Claude Code CLI: TUI rendering broken and keyboard input unresponsive on macOS

Dear Claude Code team,

I'm experiencing a severe issue with the Claude Code CLI since version 1.0.61. When I launch the CLI on macOS, the TUI layout becomes broken — box characters are misaligned, and the interface appears visually corrupted. Additionally, keyboard input does not respond: I cannot type in the input field, and Shift+Tab does not toggle the plan mode as expected.

This issue persists regardless of the following configurations:

• OS: macOS (Apple Silicon)
• Terminal: Tested with both macOS Terminal and iTerm2
• TERM: xterm-256color
• Node.js versions tried: 14.15.4, 16.15.1, 18.18.2, 22.17.1, 24.3.0
• Claude CLI versions tried: 1.0.59, 1.0.60, 1.0.61 (all show the same issue)
• Even with environment variables like FORCE_COLOR=1 or TERM=xterm-color, the issue remains

This problem did not occur before I updated the Claude CLI recently. Older versions that used to work fine now show the same behavior. I'm assuming a recent regression in TUI rendering or terminal handling might be the cause.

I'd greatly appreciate it if the team could:

1. Confirm whether this is a known issue
2. Provide any known workarounds or planned fixes
3. Let me know if I can help reproduce or debug the issue further

Thank you for your excellent work — Claude has been extremely helpful in my workflow, and I'd love to continue using the CLI.

Best regards,

Dai
