Interrupt Handling Failure: Ctrl-C Creates Newline and Blocks Input Recovery

Bug Description
Hitting Ctrl-C to interrupt Claude no longer works. Instead, it creates a newline below the entire prompt and doesn't give any way to recover. The only way to proceed is to Ctrl-C again, which ends the entire session losing all your current progress/context.
