This is a BREAKING change in the core & will require updating the clients. The way it works is instead of keeping noteIds of all the notes in the topic, it keeps an in-memory cache. This in-memory cache `topicReferences` lives in the notes collection & decouples notes from notebooks/topics. This also simplifies all the different actions where references would persist after the note was deleted. Since the note acts as the source of truth for where it currently is, there is nothing else to do except rebuild the `topicReferences` cache.
