Improvement on AvaloniaRunner, HttpServerConnection, and HostedInstanceKeeper to prevent race conditions during shutdown. Adds cancellation tokens and locking mechanisms to ensure that operations are properly stopped and resources are released in a controlled manner. Also handles a NullReferenceException during Avalonia shutdown, and avoids invoking `InstanceShutdown` or `ConnectionClosed` multiple times.
