 * @class SpatialComputing
 * INDUSTRY FIRST: Spatial Computing Framework with Native AR/VR/Mixed Reality Support
 *
 * Revolutionary spatial computing integration that provides:
 * - Native WebXR integration with fallbacks
 * - 3D spatial user interfaces
 * - Hand tracking and gesture recognition
 * - Spatial anchoring and persistence
 * - Mixed reality collaboration
 * - Adaptive rendering for different XR devices
 * - Universal compatibility (Node.js, Browser, React Native)
