BoundSphere

The BoundSphere type defines a bounding sphere for 3D space, providing efficient spatial containment, expansion, and intersection logic. It supports initialization from points, bounding boxes, and other spheres, and offers utilities for validation, distance computation, radius growth, and spatial queries. The implementation prioritizes performance, precision, and flexibility with support for custom vector types.
