示例
Prove Object3D.traverse traversal semantics in three 0.185.1: callback return values do not abort or prune traversal, mutating children during iteration throws a TypeError, and visibility flags are ignored unlike traverseVisible.

契约
- Object3D.traverse executes a pre-order depth-first traversal across all descendants and ignores boolean return values from callbacks, continuing traversal without early abort or subtree pruning.
- Object3D.traverse returns undefined rather than a chainable reference to the root object.
- Object3D.traverse visits invisible nodes and their descendants unconditionally, unlike Object3D.traverseVisible which terminates descent at invisible nodes.
- Removing a child object during Object3D.traverse throws a TypeError because the iteration loop boundary is cached at the start of traversal while the children array is mutated in place.
- Object3D.traverseAncestors walks exclusively from the parent upwards to the scene graph root, omitting the target object itself.
