- Hover provider showing entity information and type - Go-to-definition (F12) for entity references - Basic IFC file validation (ISO-10303-21 header check) - Entity parsing with regex-based detection - Proper CommonJS module system (avoiding ES module issues) This replaces the broken baseline from ifc-developer-tools which had: - Non-functional ES module configuration - Circular dependency issues - Parser crashes - Non-working PositionVisitor Built on Microsoft's LSP example template for a clean, maintainable foundation. Next: Add hierarchical entity dependency tree in hover tooltip."
