From my investigation what I know for sure:
- when the graph pans or zooms it updates the transform property on the g element, which in turn causes the browser to repaint the visible space in the g element
- stroke-dasharray is the cause of major performance issues in large graphs.
What I suspect:
- When the g element repaints, it also has to repaint all of the child svg elements. When the dashed line path svgs repaint, the stroke-dasharray calculation is not GPU accelerated, but instead occurs on the CPU, causing extreme lag whenever the svg graph is panned or zoomed.
Temporary solution: remove this dashed edge functionality. We can investigate alternatives for communicated that a path is lazy loaded.
Future long term solution: migrate to canvas based graph renderer for router tree and injector graph.

Previously, the router tree would not properly clean up css classes placed on nodes which would lead to some nodes being incorrectly visualized after each update.

Previously we would visualize route config "types" by colouring different nodes.
Now the we only colour nodes to represent the active route path. Lazy loaded routes are represented with dashed line edges that point in the direction of loading.

This updates tests and examples only to prepare for zoneless by default.
These changes were identified and made as part of #63382. Anything that
failed gets `provideZoneChangeDetection` unless the fixes were easily
and quickly determined.
It also adds the zoneless provider to the `initTestEnvironment` calls
for tests in this repo to prevent regressions before #63382 is merged.

Tests validate the current behaviour of the injector tree feature.
- Nodes should be displaying on entering the tab
- Hide framework / Hide injectors with no providers flags should filter the tree properly
- Providers side tab should be able to be opened and filtered properly using the 2 filter input fields for token and type

TransferState is only written into the DOM once during SSR and is not kept in sync with the runtime state on the client. Pressing the refresh button always re-reads the initial serialized script tag, which never changes after bootstrap.
PR Close#63592
Addresses some cleanup items for the router tree:
- No longer loads router ng global APIs as a side effect of importing the router. Rather this is now a runtime step that occurs when provideRouter is called.
- No longer depends on router.navigateByUrl in Angular DevTools. There is now a dedicated global util for this
- Router instance logic no longer depends on token name
- Prevents navigating to lazy or redirect routes (these don't have an associated component)

Fix the runtime errors caused by the tree visualizer node auto-snapping when a tab is changed. The errors are caused since we only visually hide the tabs.

signalGraphEnabled was previously passed down the component tree.
This change refactors the logic to use the settings service instead,
which already holds the value and allows sharing it across components.

Previously, Angular devtools would mistakenly traverse the same DOM elements multiple times while doing traversal for the component tree explorer. This error case would occur when more than 1 Angular application root component was present on the same page and in distinct DOM branches.
Some example cases that did work previously:
```html
<app-root>
...
</app-root>
```
```html
<app-root>
...
<app-root-2></app-root-2>
...
</app-root>
```
An example of where it would enter the irregular behaviour
```html
<app-root>
...
</app-root>
<app-root-2>
...
</app-root-2>
```
Now, we properly ignore duplicate DOM paths when looking for application and non-application root component to begin the Angular DevTools component discovery logic.

This was causing some unintended behaviour when paired with our new zoneless configuration. I'm not sure why currentlyMatchedIndex was getting set to -1 here. With this removed it seems like things are working as expected. Previously a select call would reset this index *after* a search filter was applied, which would cause weird behaviour with the "next" and "prev" buttons.

Previously these tests would run automatically when Angular DevTools lived in another repo. These files have continued to live here but have not been running automatically on each PR.
Now, these test files have been revived to run properly with our changes since the repo merge. This is a first step to reviving our e2e testing.
Next steps include writing cypress tests for new features like Injector Graph, Router tree, signals visualizations, etc.
