ConstraintGizmoSystem

Remarks

The editor's answer to "the viewport draws the goal", and a game's answer to "why is his hand through the wall on this one machine". One system, off by default, that walks the animators carrying a ConstraintStack and asks ConstraintGizmos to draw what the last solve did.

⚠ In LateUpdate, after the poses exist. Running it in the animation phase would race the very solve it is trying to show — half the characters would be drawn against this frame's answer and half against last frame's, depending on where the scheduler put them.

⚠ Only is the field that makes this usable. A scene of thirty constrained characters is a thousand lines and nothing legible; an author debugging one interaction wants one character. Left unset it draws all of them, which is right for a screenshot and wrong for everything else.
