More work on sync -- made a pretty significant change. Let's call it semi realtime sync. It's not google docs level collaborative, but updates do happen and things mostly converge. Using differential sync. For Grug purposes, it does the job -- and creates a path towards multiuser notebooks and tracking changes over time. still an mvp feature still need to match cursor position when updates happen some odd things happen if actually trying to edit exactly at the same time, but this is very much not typical use case.
