headless: interactive TTY mode (raw stdin) for driving a guest OS live
When stdin is a terminal, --headless now disables canonical mode + local echo
so keystrokes reach the guest immediately and only the guest echoes (no doubled
chars). Piped/redirected stdin is untouched (scripted input still works). Keep
ISIG so Ctrl-C quits; restore termios on exit. VMIN=1 so a no-data non-blocking
read is EAGAIN, not a 0-byte read the serial layer would misread as EOF.
