deps/CMakeLists.txt only extracted CGAL when WITH_CGAL=ON.
With -DWITH_CGAL_TESTS=ON the CGAL include path was never populated,
causing fatal error: CGAL/Simple_cartesian.h: No such file or directory.
Fix: extract CGAL-6.1.1 for both WITH_CGAL and WITH_CGAL_TESTS.

macOS filesystem is case-insensitive so both spellings worked locally,
but the Linux container (CI) could not find the file and failed with
"does not contain a CMakeLists.txt file".

Restructures the CMake build into three clearly separated modes:
(default) tests only – Eigen + GTest, no heavy deps
-DWITH_VIEWER=ON builds viewer lib (libigl / GLFW / GLAD)
-DWITH_CGAL=ON builds conformallab_core CLI app;
implies WITH_VIEWER automatically
Changes:
- code/CMakeLists.txt: viewer and core targets are now guarded by
option() flags; GTest / tests target is always built
- code/deps/Cmakelists.txt: CGAL, libigl, glfw, glad are only
extracted when the corresponding mode is enabled; Eigen always
- Remove Boost (211 MB tarball, 0 usages in the codebase – CGAL 6.x
does not require Boost for Simple_cartesian / Surface_mesh / basic IO)
- Remove code/src/main.cpp (dead file, not referenced in CMake)
All 16 C++ tests pass in tests-only mode (verified locally).
