feat(spatial): add BVH spatial indexing (#664)

- Add `FollowClosestPlayer` component to make `/spawn` entities follow
the nearest player
- Move `PlayerBoundingBoxes` from `hyperion` into new `spatial` crate as
`SpatialIndex`
- Change `get_collisions` to return iterator instead of using callback
- Update Rust nightly from `2024-11-29` to `2024-12-07`
- Fixes #665
