/**
 * Represents the detailed data of a single contact point between two rigid bodies in the physics
 * simulation. This class provides comprehensive information about the contact, including the
 * entities involved, the exact contact points in both local and world space coordinates, the
 * contact normal, and the collision impulse force.
 *
 * Instances of this class are created by the physics engine when collision events occur and are
 * passed to event handlers only through the global `contact` event on the
 * {@link RigidBodyComponentSystem}. Individual rigid body components receive instances of
 * {@link ContactResult} instead.
 *
 * @example
 * app.systems.rigidbody.on('contact', (result) => {
 *     console.log(`Contact between ${result.a.name} and ${result.b.name}`);
 * });
