BoundRect

The BoundRect type defines an axis-aligned bounding rectangle for 2D space, providing efficient spatial containment, expansion, and intersection logic. It supports initialization from points, circles, and other bounding rectangles, and offers utilities for validation, distance computation, ray intersection, and spatial queries. The implementation prioritizes performance, precision, and flexibility with support for custom vector types.
