Implements tscircuit/tscircuit#758 by adding comprehensive GLTF loader functionality. Features: - GLTF 2.0 file format parsing with base64 buffer support - Triangle mesh extraction from GLTF primitives - Coordinate system transformation (Y-up to Z-up) - Integration with existing STL/OBJ pipeline - Comprehensive error handling and input validation - Performance caching and optimization - 91 test cases with 1,057 assertions across 13 test files Core Implementation: - lib/loaders/gltf.ts: GLTF parser with buffer decoding - lib/types.ts: GLTFMesh interface integration - lib/converters/circuit-to-3d.ts: Pipeline integration - lib/gltf/geometry.ts: Mesh creation utilities Testing Coverage: - Unit tests: Core parsing, triangulation, edge cases, security - Integration tests: End-to-end workflow validation - Performance tests: Caching and memory efficiency - Error handling: Malformed data and network failures 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
