Workcat: cute desktop cat, no window closing

Reworks the example into a pure desktop-pet: the cat wanders, sits, grooms,
stretches, dashes and naps, reacts to petting and dragging, and follows the
cursor with its eyes. The window-scanning and Accessibility code is gone.

The cat is drawn from rounded primitives plus Shape paths in a fixed 100x90
design space, so it scales cleanly to any size.

Linux/X11 is the primary target: the tray is optional, Wayland gets a warning,
and WORKCAT_X11_BYPASS / WORKCAT_OPAQUE cover uncooperative window managers.
