Pure-Wren glTF 2.0 / .glb loader. Parses the binary container into nodes / meshes / materials, resolves accessors into typed vertex + index arrays (Float32Array / Int32Array / ByteArray), decodes embedded images via @hatch:image, and spawns a Transform-rooted hierarchy into a @hatch:ecs World with fully-textured PBR Materials wired to every glTF slot (baseColor / metallicRoughness / normal / occlusion / emissive).
