Rewrite _traverse_xcaf → _author_xcaf_to_usd that recursively authors USD prims mirroring the XCAF assembly tree: - Assembly nodes become UsdGeom.Xform prims with local transforms from each component label's Location (not composed with parents) - Leaf shapes get definition-space vertices (face_loc only, no instance placement) — the USD scene graph composes transforms hierarchically - Coordinate swap (X,-Z,Y) now authored once as a root Xform on /Root/Assembly instead of per-vertex transformation - Sharp/seam edges extracted per-part from definition shape (not global) This fixes misplaced geometry for sub-assembly parts (e.g. KOMP-EIN roller cages with -45° Z rotation) that were previously lost by the flat traversal.
