Changed the `AllocationManager` initialization to specify size in `Program.cs` and commented out the disposal of `unfreeArray`.
Changed `UnsafeArray` to use `AllocationManager.Realloc` for memory reallocation.
Changed constructors of `UnsafeHashMap` and `UnsafeHashSet` to include an `AllocationOption` parameter for improved memory management.
Added a `Remove` method to `UnsafeHashMap` for key-value pair removal.
Changed `AllocationManager` to use a hash map instead of a queue for managing allocations.
Added a `Realloc` method in `AllocationManager` for handling memory reallocation.
Changed the `Free` method in `AllocationManager` to iterate through the hash map for freeing allocated memory.
