- Fix GCC -O2 warnings: calloc for cf (maybe-uninitialized), suppress stringop-truncation/alloc-size-larger-than (false positives), guard louvain against negative node_count - Default compiler: cc on macOS, gcc on Linux/Windows (fixes gcc-14 not found on MSYS2) - Docker test infra now runs BOTH test (ASan) and build (-O2 -Werror)
