Solution

Use a recursive graph traversal starting from `source.Root` — For each object, walk all `Rigidbody.Joints` and `Collider.Joints`. Tension: Also walk `ManualLink` components for non-physics connections. Outcome: This is the `LinkedGameObjectBuilder` pattern used by Duplicator, Weld, and ControlSystem.
