what_changed

Find out what happened on this board while you were not looking. Pass the `asOf` or `cursor` you were given last time as `since`, and you get back every change made in between — who made it, what it was, and which notes it touched — instead of having to keep an old get_scene and diff it by hand. Anything marked `mine: false` was another participant or their agent: it is their work, not a stale copy of yours, so read it before you rearrange or undo it. Call this after any pause, and after any call that took longer than you expected. Calling it with no `since` gives you a starting cursor rather than the whole session.
