feat(buffer): add allocation tracking and diagnostics

Add AllocationManager.GetTotalAllocatedMemory() to track total allocations when safety checks are enabled. Improve diagnostics by calling Debug.Fail in Dispose methods of HashMapHelper, UnTypedArray, and UnsafeArray when disposing uninitialized or already disposed arrays. Remove AddRange(ReadOnlyUnsafeCollection<T>) from UnsafeList<T>. Increment assembly version to 1.6.4. Ensure arrcpy is disposed in Program.cs.
