The code has been simplified to no longer use a dictionary to manage multiple instances of `Singleton<T>`. Now a single instance of `T` is used via a static `Instance` property.

The `Create` method has been changed to set the instance if it is not already set, and a new `Destroy` method has been added to reset the instance to `null`.

The `TryGet` and `Destroy` methods have been simplified to work with the new single instance implementation.

The calls to `Singleton<VirtualPlugin>.Create(this)` and `Singleton<VirtualPlugin>.Destroy(this)` in `VirtualPlugin.cs` have been commented out, with annotations suggesting that use of the class itself as a singleton might require a different approach to avoid overwriting other instances.
