Summary:
Listen to framework events and store in a map based on node id
Added UI to allow for monitoring framework event types.
The event type is a string separated by : Each segment of this string represents a level in the dialog hierachy. For example Litho:Layout:StateUpdateSync would have levels, Litho Layout StateUpdateSync
When event type monitored and event comes in for a node flash the visualiser node briefly

Summary:
The root view resolver will always find all root views but there was a bug in the listrootviews method. The code was very complex and most of the code seemed to be unneeded. Its now working. The listrootviews method now just returns teh contents of the observable array.
The reason we needed this is that Certain activities dont seem to tracked by the listener we add to `registerActivityLifecycleCallbacks` Its as if there is a floating decor with no activity. One example in FB4a is clicking on a notification in the notifications panel

Summary: With the previous approach it was hard to read the name of the node, this should be a lot clearer. The tool top comes in a after a delay, the reason for this is because when i tried without a delay when you moved the mouse fast a ton of tooltips would appear and disappear when you passed over diffferent nodes and it was very distracting. 200ms seems to be about the sweet spot

Summary: If a node has a global negative offset (e.g from a view pager) its position will be outside of the visualizors bounds and could potentially be where the tree is. The user doesnt see the wireframes since overflow hidden is on the parent node. A situation can arise where when the mouse is over the tree the hit test returns an offscreen node and causes us to hover a random node rather than the tree node hover effect taking place. We are just adding a guard to say if the mouse is outside the dom rect for the root visualization node than dont run the hit test

Summary:
Previously we would only consider a node hit if the nouse pos was inside every parents. There are a few reason why this isnt ideal:
1. Fragments are return 0 bounds
2. Many hierachys (particually in litho ) have nonsensical strucutres where your parent may have hieght 0, or children overflow parents bounds. Therefore it was impossible to select many nodes but unclear why

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:
Clicking on a node a second time will unselect which was impossible before.
The behaviour of the on click handler doesnt always line up what is currently hovered, this is a temporary work around. There are deeper issues with this in that on exit we hover the parent, but in some situations the parent is too small to propagate. In future we will use the mouse position and do a hit test and drive selection / hover from that

This change allows to take different snapshots for different nodes and render them each on the visualiser.
At the moment, more than likely, this is not really used. At the same time, it fixes an issue whereas any subtree update can override and set the only visible snapshot.

Summary:

TODO: the snapshot corresponds to the referring subtree update. However, the snapshot is getting applied as if it was the current top view of the running app. This is true in most cases but it doesn't for some. To solve this, we need to use the rootId for the subtree and apply the snapshot only if appropriate.
Having said that, is good enough for the current submission as we keep iterating on it.

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
