The §79 serializer for Collider (§24, §25, PH-17).
The collider's body is not saved and does not need to be: Collider.body
resolves lazily from the scene graph — the RigidBody on its own node, else
the nearest ancestor's — so rebuilding the hierarchy rebuilds the association.
A solver handle would be world-registration state, which is exactly what a §79
document must not carry.
