* [M1-02] Native memory arenas + 64B cache-aligned Flecs hooks - LinearFrameAllocator: lock-free atomic bump pointer, per-frame reset. - PageArenaAllocator: mmap/VirtualAlloc reserve + lazy commit, lock-free bump with spin-serialized page commit. - Aligned Flecs hooks: ecs_os_api malloc/calloc/realloc/free wrappers enforcing 64B payload alignment via one-line header; arena-backed with aligned_heap fallback. - Single-universe link: flecs_static default visibility + WHOLE_ARCHIVE into libengine_core so tests bind the .so's ecs_os_api (dual-copy segfault root-caused: exe read NULL hook table from its own fragment). - CTest engine_memory_arenas: 45 checks covering all acceptance criteria. Verified: linux-debug/linux-release/ci-linux builds zero-warning (-Werror), ctest 2/2 green, ASan+UBSan clean. 1M-row warm sweep (release): 1.62 ms single-threaded C++; side-by-side stock malloc 1.40-1.62 ms vs hooked 1.62-1.74 ms at -O2 (allocator overhead at noise level; absolute 1.5 ms gate owned by M1-05 workers+SIMD). * fix(ci): silence intentional C4324 padding on Transform64 (MSVC /WX) * fix(windows): ENGINE_CORE_API export macro for allocator/hook symbols * fix(review): single shared flecs universe, subtraction bounds checks, export macro * fix(windows): scope C4251 suppression to exported allocator classes * fix(ci): pin msvc-dev-cmd to full SHA (S7637) * fix(sonar): nested comment on intentional no-op deallocate (S1186) --------- Co-authored-by: hermes-agent <hermes-agent@local> Co-authored-by: hermes <[email protected]>
