- Add Google Test via CMake FetchContent (v1.14.0) - Add clausen.hpp: Clausen integral, Lobachevsky function, Im(Li2) - Add hyper_ideal_utility.hpp: generalized and ideal-vertex hyperbolic tetrahedron volume formulas using Eigen for the 4x4 Gram determinant - Port ClausenTest (5 tests) and HyperIdealUtilityTest (8 tests) from Java/JUnit — all 13 pass with same tolerances as the Java originals - Fix pre-existing VIEWER/viewer case mismatch in CMakeLists.txt Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
