[Bug] Hard lockup with unresponsive UI and infinite status bar animation

Bug Description
The last several versions of Claude Code have had hard lockup issues that have forced me to close my terminal window. Escape and Ctrl+C repeatedly do nothing. The UI responds to no feedback at all and the green "cylon" status bar never stops.

Environment Info

• Terminal: iTerm.app
• Version: 2.1.44
