When building the tree, I've implemented a few improvements:
- We no longer traverse the full ancestry for every leaf node- we exit
early when we find a node that already exists
- We no longer search the entire tree to see if a node id exists before
creating one with that id, we just check if is in the map
- Reconciler now has precommit and postcommit hooks for patch applying
- This is used to compute a patch tree snapshot precommit and update the
tree metadata postcommit
- PatchVisualizer can now display Removes that happened during sync
- It was previously missing because the removed objects no longer
existed so it couldn't get any info on them (This is resolved because
the info is gotten in precommit, before the instance was removed)
- PatchVisualizer now shows Old and New values instead of just Incoming
during sync
- (Still displays Current and Incoming during confirmation)
- This is much more useful, since you now see what the changes were and
not just which things were changed
- PatchVisualizer displays clarifying message when initial sync has no
changes instead of just showing a blank box
- Objects in the tree UI no longer get stuck expanded when the next
patch has the same instance but different info on it
- Objects in the tree UI correctly become selectable after their
instance is added and unclickable when removed during sync
