Major refactor of job system and memory allocator: - Replaced threadIndex with preferLocal for scheduling - Switched local queues to SPMCQueue for better performance - Introduced lock-free JobEdge pool for dependencies - Removed remainingBatches; use ref counting for completion - Updated all scheduling APIs and tests to new model - Optimized FreeList struct sizes and block management - Added allocation benchmarks - Disabled OwnershipTransferAnalyzer temporarily - Bumped assembly versions
