Description
Currently, the outline of the unit does not matter for selecting it.
We have to build the renderer (#34 #286 #287) in such a way we can tell which pixel belonged to what unit.
This allows us to click anywhere in the game and then determine what object was drawn there.

Research direction
Begin with the renderer work referenced by #34, #286, and #287, then read the linked OpenGL object-selection and raycasting tutorials to understand the intended approach. Done means a click at any game pixel identifies the unit or object drawn there rather than relying on its outline; no file or test is named in the issue.
