Repin OCCTSwift floor from 1.15.10 to 1.17.0, picking up Pass 1a of OCCTSwift's #377/#380 duplication/bug-fix audit. No API or behaviour change here (Surface.drawMesh/evaluateGrid, the one real break, is unused in this package). Note: v1.7.1 was documented but never tagged — see CHANGELOG. See docs/CHANGELOG.md for details.
