  ⏵⏵ bypass permissions on (shift+tab to cycle)

Claude Code has been suspended. Run `fg` to bring Claude Code back.
Note: ctrl + z now suspends Claude Code, ctrl + _ undoes input.
fg

No shell, nothing. Also, Ctrl-Z should not be for suspension after having been so long a useful hotkey, and remains a hot key in other terminal edits. This is a bad change.

What Should Happen?

Ctrl-Z should be reverted. As for command suspension, it should drop back to shell, timeout, or error.
