Rather than try to track the transition state, which was proving
unreliable, I am just directly tracking the node state and determining
whether to debounce the inner rect based on whether the user has the
prefers-reduced-motion setting or query, whether the node is resizing,
and whether it's currently magnified. I'm then using the actual
animation time setting to determine how long to debounce.
This handles an edge case where a user deletes all unmagnified nodes,
leaving a final node that is still magnified. Because we ignore
magnify/unmagnify operations when there's only one leaf remaining, this
would result in the last node being stuck magnified until a new node is
added.
Also fixes a bug where the layout would not always update when a new
block was added.
Rather than using a timeout to debounce changes to the
NodeModel.innerRect, I'll use a transition event on the display
container. This way, if the user disables transitions using the reduced
motion setting, changes to the innerRect value will not be debounced.
Adds a flag to the insert layout action to explicitly set the focus of a
newly inserted node. This also adds a flag in the starter layout to
focus on the terminal block.
Make the block content sizing update once when its node moves or becomes
magnified. By manually updating this inner sizing rather than letting
the block flow in the DOM, the animations of the block frames are much
smoother.
This also fixes an issue where two scrollbars were being rendered for
the Directory Preview widget.
This also sets zero padding on nodes when there's only a single node
being rendered.
This adds a new NodeModel, which can be passed from the TileLayout to
contained blocks. It contains all the layout data that the block should
care about, including focus status, whether a drag operation is
underway, whether the node is magnified, etc.
This also adds a focus stack for the layout, which will let the focus
switch to the last-focused node when the currently-focused one is
closed.
This also addresses a regression in the resize handles that caused them
to be offset from the cursor when dragged.

This PR is a large refactoring of the layout code to move as much of the
layout state logic as possible into a unified model class, with atoms
and derived atoms to notify the display logic of changes. It also fixes
some latent bugs in the node resize code, significantly speeds up
response times for resizing and dragging, and sets us up to fully
replace the React-DnD library in the future.
