ValueChangedMessage
ValueChangedMessage is a built-in BaseMessage used when a Message Broker broadcast represents a change from one value to another.
It carries both the previous and new value, making the intent of the payload explicit to subscribers. Although the same data could be represented using ValueMessage<T1, T2>, ValueChangedMessage should be preferred for value-change notifications because it clearly identifies which value represents the previous state and which represents the new state.
