PlaySystemOrder

Remarks

⚠ Registration order is the tie-break and the default, deliberately. A sort that reordered contributions with nothing to say about each other would make the frame depend on a hash order and turn every existing comment about sequence into a lie. With no attributes anywhere this returns exactly what it was given, which is what every contribution in the tree got before the attributes existed.

⚠ It cannot move the snapshot. PlayModeController.Play captures the world and *then* calls Contribute; this runs inside that call, so everything a contribution creates is still outside the snapshot and still goes away with a Stop. An ordering mechanism that ran earlier — at registration, say — would be the one change that could move that boundary, which is why the sort is here and not in IEditorRegistry.Add.

  Sorts contributions so that a provider attaches before anything that asked for it.
