//! IFC5 (IFCX) JSON format parser
//!
//! This module handles parsing of IFC5 files which use a JSON-based format
//! with Entity Component System (ECS) composition model.
//!
//! Key differences from IFC4 (STEP):
//! - JSON format instead of STEP text
//! - Path-based UUIDs instead of Express IDs (#1, #2, ...)
//! - Pre-tessellated USD geometry instead of parametric
//! - Flat namespaced attributes instead of explicit relationship entities
//! - ECS composition via `children` and `inherits`
