switched exec-cycle to a live >=2fps ascii preview loop and added txt2printr stub

replaced the guvcview+keypress capture flow with a continuous
capture/convert/display loop so the terminal shows a live ascii
preview; pressing c saves the frame and triggers the new
txt2printr.sh hook (currently a blank template).
