New files: - gauss_bonnet.hpp: euler_characteristic, genus, Σ(2π-Θ_v) sum/rhs/deficit, check_gauss_bonnet (throws), enforce_gauss_bonnet (correct sign: Δ=(lhs-rhs)/V) - cut_graph.hpp: CutGraph struct + compute_cut_graph (tree-cotree, Erickson–Whittlesey 2005); boundary edges correctly excluded from cut set - test_phase6.cpp: 26 new tests (GaussBonnet ×8, CutGraph ×6, HyperbolicTrilateration ×4, Normalisation ×4 — all pass) layout.hpp (Phase 6 rewrite): - detail::trilaterate_hyp: exact Möbius + hyperbolic law of cosines replacing old tanh(d/2) - detail::center_poincare_disk: Möbius centering for hyperbolic normalisation - normalise_euclidean: centroid → origin + PCA major-axis rotation - normalise_hyperbolic: Möbius centering in the Poincaré disk - normalise_spherical: Rodrigues rotation → north pole - euclidean_layout / hyper_ideal_layout: optional CutGraph* + HolonomyData* + normalise Bug fixes caught by new tests: - gauss_bonnet.hpp: enforce_gauss_bonnet had wrong sign for delta - cut_graph.hpp: boundary edges were incorrectly marked as cut edges 121 tests pass, 2 skipped (Hessian stubs).
