Bend the torso from the hips and add bow and twerk test animations

- LimbBend.anchoredAtEnd keeps the far end in place (the hips on the legs) and folds the other half, and angleAt/axis expose how far the limb has turned at a point. - PoseApplier bends the body from the hips and carries the head and arms with it: their pivots follow the bent torso and they turn with its ring. - Test animations: bow (torso only) and twerk. The gametest shoots the twerk at the top and bottom of its bounce, including from behind. Co-Authored-By: Claude Opus 5.5 <[email protected]>

+The torso is anchored at the hips instead of its pivot (`LimbBend.anchoredAtEnd`), so the legs stay
+attached and the chest leans. The head and arms are siblings of the body in the vanilla model, so
+`PoseApplier` carries them: their pivots follow the bent torso, and they turn with its ring there
+(`LimbBend.angleAt`). An arm carried by a forward lean swings back like a diver's, so emotes that want
+hanging arms tilt them forward by about the lean (see the `twerk` test animation).

+Held items still attach to the unbent arm, and the cape doesn't follow the torso yet.
