Introduction to cache coherence: false sharing, MESI protocol and vectorization

Custom multithreaded C++17 memory allocator: thread-local lock-free pools over a locked central heap, global new/delete override, constexpr compile-time fragmentation detection, and a real-time ImGui visualizer. ~3-4x faster than malloc.
