Replace URL-based active route detection with direct traversal of the ActivatedRoute tree.
This solution is more reliable than the previous approach because it directly compares router tree configuration objects against the active router instance state with router.routerState.
Previously we would look in the DI tree for a token named 'Router' and resolve its value.
Now we use the already existing getRouterInstance, which depends on ng global debug APIs to get the router instance of an application.
Previously '/' could cause confusion with other routes that use a path here. I think because this node is unique in that it is not actually a "Route" we should make it clear with the label that is simply the App Root.
Adding some typing to infer the expected types and drop the usages of `arguments` which isn't really typesafe.
The argument mis-match didn't result in an issue because they didn't end up being used futher down the line.

Previously this would take ~3500ms adev.
This updated logic avoids the constant JSON.stringify implementation and instead checks for serializable values directly.
After this change this code path for adev takes less than 20ms.

This commit updates the TypeScript configuration across the project to use `moduleResolution: "bundler"`. This modernizes our module resolution strategy to align with current TypeScript best practices and bundler behaviors.
The following changes are included:
- Updated `tsconfig.json` files to set `moduleResolution` to `"bundler"`.
- Updated the `rules_angular` bazel dependency to a version compatible with these changes.
- Adjusted related test files and golden files to reflect the new module resolution strategy.

Some properties (like gets) might throw when we try to read them.
With this commit we fail gracefuly and show a warning message for the property that can't be read.

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)

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.

Previously in DevTools we would read signal values to display preview values in the UI without safely catching any errors thrown in their evaluations.
Now those signal functions are run in a safe context, their errors are caught and handled in the UI as well as replayed in the console.

On clicking a route in the router tree, the route details panel is displayed.
- The panel shows the details of the selected route, including the path, component, providers, guards etc.
- Clicking on a chip will navigate to the corresponding source file in the editor.
- Clicking on the path will navigate to the corresponding route in the router tree.
