In the Angular DevTools Chrome DevTools page:
- Angular DevTools is able to ask the background script to list each frame that has been registered on a page.
- Angular Devtools is able to ask the background script to "enable" the connection on a particular frame. This enables the messaging between the content script <-> background script <-> devtools page
- Implements detection of non unique urls on the inspected page
Limitations:
- The `inspectedWindow.eval` API is only able to target frames by frameURL. This means some features that integrate with Chrome DevTools like inspect element and open source will not be available when inspecting frames that do not have a unique url on the page.

Modifies the messaging layer of devtools to allow for switching communication between frames on a page. When served as a browser extension.
Design:
- When a page renders, DevTools installs a content script onto it through it's manifest file. The all_frames option is used here to install this script onto every frame in a page.
- When Angular is detected, the content script will install a backend script into it's frame.
- Each content script / backend script pairing is kept track of in the background script. This pairing represents an angular devtools context in a particular frame.
- Angular DevTools is able to ask the background script to list each frame that has been registered on a page.

When the linker is running using an unpublished version of angular, locally built, the version will be `0.0.0`.
When encountering this situation, the range that for the linker map support is considered to be `*.*.*` allowing
for the linker to work at build time with packages built with versioned angular.
Most notably this allows for us to properly use the linker in building our documentation site with the locally
built version of angular.

The version detection condition for signal two-way bindings used an OR
instead of an AND, resulting in every `.0` patch version being considered
as supporting two-way bindings to signals.
This commit fixes the logic and adds additional parentheses to ensure the
meaning of the condition is more clear. Long term, we should switch to
semver version parsing instead.
PR Close#54443
In order to allow both signals and non-signals in two-way bindings, we have to pass the expression through `ɵunwrapWritableSignal`. The problem is that the language service uses a bundled compiler that is fairly new, but it may be compiling an older version of Angular that doesn't expose `ɵunwrapWritableSignal` (see https://github.com/angular/vscode-ng-language-service/issues/2001).
These changes add a `_angularCoreVersion` flag to the compiler which the language service can use to pass the parsed Angular version to the compiler which can then decide whether to emit the function.

Currently all triggers are set up to show the placeholder block on the server, except for `on immediate` which is basically a noop. These changes update `on immediate` to match the rest of the triggers.
Fixes#54385.

Getting the typing for `ɵunwrapWritableSignal` just right was tricky so these changes add some tests to ensure that we don't regress.
Also reworks the type tester a bit to make it easier to find where to add new test files.

This commit updates the implementation of the `customElements` patch and also
patches FACE callbacks (`formAssociatedCallback`, `formDisabledCallback`, `formResetCallback`
and `formStateRestoreCallback`). This now allows invoking those callbacks in the same zone
where the custom element has been defined.

Assure that the same readonly array corresponding to the children query results
is returned for cases where a query is marked as dirty but there were no actual
changes to the content of the results array (this can happen if a view is added
and removed thus marking queries as dirty but not influencing final results).

Currently we have two fake copies of `@angular/core` in the compiler tests which can be out of sync and cause inconsistent tests. These changes reuse a single copy instead.

This updates some tests to use the public imports from `@angular/core` now that they are available,

In some situations, calling `markForCheck` can result in an infinite
loop in seemingly valid scenarios. When a transplanted view is inserted
before its declaration, it gets refreshed in the retry loop of
`detectChanges`. At this point, the `Dirty` flag has been cleared from
all parents. Calling `markForCheck` marks the insertion tree up to the
root `Dirty`. If the declaration is checked again as a result (i.e.
because it has default change detection) and is reachable because its
parent was marked `Dirty`, this can cause an infinite loop. The
declaration is refreshed again, so the insertion is marked for refresh
(again). We enter an infinite loop if the insertion tree always calls
`markForCheck` for some reason (i.e. `{{createReplayObservable() | async}}`).
While the case above does fall into an infinite loop, it also truly is a
problem in the application. While it's not an infinite synchronous loop,
the declaration and insertion are infinitely dirty and will be refreshed
on every change detection round.
Usually `markForCheck` does not have this problem because the `Dirty`
flag is not cleared until the very end of change detection. However, if
the view did not already have the `Dirty` flag set, it is never cleared
because we never entered view refresh. One solution to this problem
could be to clear the `Dirty` flag even after skipping view refresh but
traversing to children.
