  Revert the curs_kbhit() peek into the curses input queue (#1223)  
    
  Reverts 826514e723 (hang-4-prevention, 2026-08-10).  It does not fix the  
  input lag it was written for.  
    
  That lag is not a curses buffering problem.  Inside GNU screen, once the  
  application enables mouse reporting (DECSET 1000, 1002 or 1003), screen  
  holds a trailing ESC byte and releases it only when the next input byte  
  arrives, so the ESC never reaches the descriptor and no amount of asking  
  curses for it helps.  A raw stdin reader with no curses linked in shows  
  the same hold, and the hold is unbounded - measured past 10 seconds.  
  tmux does not do this.
