/**
 * Casts a ray in the world using the spatial partition for broad-phase, then shape-specific narrow-phase.
 * Direction will be normalized internally.
 *
 * @param partition - Spatial partition to query
 * @param origin - Ray origin
 * @param direction - Ray direction (any length)
 * @param maxDistance - Maximum distance
 * @param mask - Optional collision mask (layer)
 * @param filter - Optional filter function (return true to include entity)
 * @returns Nearest hit or null
 *
 * @example
 * ```typescript
 * const hit = raycast(worldPartition, new Vector2(0,0), new Vector2(1,0), 1000);
 * if (hit) {
 *   // handle
 * }
 * ```
