Show HN: Hexecute, a gesture-based Wayland launcher

Hexecute is yet another Wayland launcher, but using gestures instead of a menu to select options!

This started as a silly project for a 10hr hacking challenge (the theme was "magic"), but the end result was a lot more usable than I expected.

Stroke recognition is performed using the $1 Unistroke Recognizer algorithm from the University of Washington.
