Phase 5 complete: layout.hpp - euclidean_layout(): BFS unfolding in ℝ² using trilaterate_2d - spherical_layout(): BFS on S² using trilaterate_sph (spherical law of cosines) - hyper_ideal_layout(): BFS in Poincaré disk (tanh(d/2) Euclidean approx) - save_layout_off(): convenience OFF writer for 2-D and 3-D layouts serialization.hpp - save/load_result_json(): nlohmann/json; stores DOF vector + uv/pos layout - save/load_result_xml(): hand-written writer/parser; same schema conformallab_cli.cpp (rewritten) - CLI11 interface: -i/-o/-g/-j/-x/-s/-v - Dispatches to euclidean / spherical / hyper_ideal pipeline - Runs Newton, computes layout, saves OFF + JSON + XML examples/example_layout.cpp - Full round-trip demo: solve → layout → JSON/XML → reload → verify tests/cgal/test_layout.cpp (8 tests) - Euclidean_PreservesEdgeLengths, CorrectVertexCount, TriangleIsNonDegenerate - Spherical_PreservesArcLengths, PositionsOnUnitSphere - HyperIdeal_SuccessAndFinitePositions - Serialization.JSON_RoundTrip, XML_RoundTrip All 95 CGAL tests pass (2 skipped — Hessian stubs unchanged).
