Function proximity_components

pub fn proximity_components<A, B>(
    first: &A,
    second: &B,
    threshold: f64,
) -> Result<Vec<ProximityComponent>, MeshProximityError>
where
    A: TriangleMeshView + ?Sized,
    B: TriangleMeshView + ?Sized,

Disjoint regions where two meshes approach within threshold.

Two close pairs belong to the same component when they share a triangle on either mesh; connectivity is transitive through that relation. This groups one physical approach into one component instead of reporting every triangle pair separately.

Components are ordered by closest approach, nearest first, with ties broken on the witness triangle indices so the order is reproducible.
