Crate rustsim_geometry 

Geometric primitives and queries for rustsim.

This crate is intentionally tiny and dependency-free. It provides:

• Vec2 and Vec3 type aliases over [f64; 2] and [f64; 3] with free-function arithmetic in the vec2 and vec3 modules.
• Axis-aligned bounding boxes Aabb2, Aabb3.
• Segments Segment2, Segment3 with closest-point queries.
• Rays Ray3 and planes Plane3 with ray-plane intersection.
• Triangles Triangle3 with closest-point and ray-triangle intersection (Möller–Trumbore).
• Spheres Sphere3 with sphere-vs-AABB / sphere-vs-triangle tests.

All functions are f64. No unsafe. No external crates. No allocation in hot paths.
