feat(allocator): add per-thread caches to FreeList

Browse Source 
Refactored FreeList allocator to use per-thread caches for improved scalability and performance, with configurable max concurrency and overflow cache. AllocationManager debug layer is now compile-time via ENABLE_DEBUG_LAYER. MemoryUtility methods no longer catch exceptions. Argument validation standardized with ThrowIfNegative. JobScheduler passes maxConcurrencyLevel to allocator. CollectionUtility's GetElementUnsafe returns mutable ref. AssemblyVersion incremented. Added comprehensive FreeList unit tests. Improved robustness and error handling in allocation classes.

BREAKING CHANGE: Debug layer APIs removed; FreeList allocator interface changed for thread cache support.
