feat(packages): ludic.aim - what the crosshair is on: a ray through the middle of the screen against upright cylinders widened by a fixed angular forgiveness, the nearest one the ground does not hide, reach floored at three metres, and which thing the use key means (that, nothing and say why, or the nearest); the probe of the ground's own answer against the aim; the camera, the ground and the body through a port
