- JobSystem abstraction over the existing ThreadPool worker pool; the factory in JobSystem.cpp is the single backend switch point (TBB later). - Job carries a dependency count and completion callback so a render graph can be wired on top without rewriting the scheduler. - parallel_for(first, last, body, chunk) with static partitioning, auto chunk sizing, and a join handle; task_group provides fork/join with help-execution so workers can wait without deadlocking. - Per-frame arena (beginFrame/endFrame) for frame-scoped jobs: no per-frame new/delete; frame jobs are recycled by the arena. - Thread module exposes a shared engine JobSystem (getJobSystem). - VoxelWorld::remeshDirty now uses parallel_for instead of raw std::thread. - 24 new zeroerr tests in test/thread.cpp; verified with a standalone MSVC harness (24 cases x 30 runs, no flakes).
