Summary: Out of the box the library search has some issues. when search matches it steals focus from the input. Eventually we want to customise the rendering of the tree items anyway so this lays the foundation for taht

Summary:
There are situations where multiple siblings overlap and they are both hit. Previously we picked the first one in the hierachy. Now we produce a list of hit children. The list will not have 2 nodes in the same ancestor path.
We store the hovered nodes as a list as we may want to present a modal in future to ask user which node they indented to select. That said simply sorting nodes by area seems to give decent results so we can start with this

Summary:
The Dom events for the divs that are very close together were not firing correctly causing the old implementation to not track the hovered node correctly. This was really frustrating trying to select a node amongst many close neighbours.
The new approach uses the mouse x,y position and performs a hit test. Currently we do a dfs looking for the first deepest child that interests the mouse x,y. In a future diff we will extract a list when there are multiple candidates.
Hovered node was removed from react props since both the tree and visualisor depend on it meaning when hover state changes the whole app is rerendered. Instead we have moved hover state to an atom which is subscribed to by each visualsation node. Only if the old or new value matches the particular nodes id do we set state. The viz nodes were memo'd to prevent children renderning. The result is that for a hover change at most 2 nodes out of the 500 or so will rerender.
I attempted to do the same with the tree but it wasnt working with the controlled tree environment + focus state. The perf seems fine as is so will leave it for now

Summary:
Upgraded from ant tree library to the much more capable React complex tree. Added the following:
1. Ability to expand / collapse nodes while automatically expanding / collapsing active/inactive children when they change
2. Keyboard controls of tree all the time
3. Basic search functionality
4. Selecting node in tree focuses and scrolls in the tree
5. Hover state for tree

Summary: We have a list of modules that we do not bundle with the plugins, but provide externally to them from Flipper. For the mechanism to work correctly, we have to stop importing from nested paths of these modules.

Summary:
Improved the 2 way relationship between tree and vizualiser. There are 3 states.
1. Select, this is when you click on either tree node or view. View is highlighted darker colour, sidebar shows up for that node and select is persisted when you mouse away
2. Hover, this is when you hover over a tree node or in the vizualizer, the node is highlighted a lighter colur
3. Hover while holding control - same as hover but we dont draw any children, this lets you see how parent nodes appear without their children

Summary:
Introduced some basic bidirectional link between tree and wireframe, the specific interaction will need some tweaking but this should get us started.
When hovering over the tree we halt the rendering of the wireframe up to that point, this allows us to explore parent views that layout child views.
When clicking a view in the wireframe it is 'seleceted' as if it was clicked in the tree. This set the tree selection so you can identify it in the tree as well as opens the side bar
