Every module unit now includes the standard headers it uses. Declarations reaching a unit only through an imported module's global module fragment are reachable but not visible, so ADL misses the free operators older libstdc++ declares beside a type - reproduced on ubuntu 24.04 (libstdc++ 13), where gl/vao.cpp could not compare vector iterators. Also drops a stale editor/editorSettings.hpp from the MSVC source list, which broke the Windows configure step, silences the deliberate include-in-purview warning in the glm wrapper, and removes GCC support: clang or MSVC only.
