By default, `toSignal` transforms an `Observable` into a `Signal`, including
the error channel of the Observable. When an error is received, the signal
begins throwing the error.
`toSignal` is intended to serve the same purpose as the `async` pipe, but
the async pipe has a different behavior with errors: it rejects them
outright, throwing them back into RxJS. Rx then propagates the error into
the browser's uncaught error handling logic. In the case of Angular, the
error is then caught by zone.js and reported via the application's
`ErrorHandler`.
This commit introduces a new option for `toSignal` called `rejectErrors`.
With that flag set, `toSignal` copies the async pipe's behavior, allowing
for easier migrations.

DEPRECATED: NgProbeToken
The `NgProbeToken` is not used internally since the transition from View Engine to Ivy. The token has no utility and can be removed from applications and libraries.

Phase 2 sample code conversions per instructions in doc: https://docs.google.com/document/d/1QqnVK8Mc0O1gU9ctPrs-JJ42V9_dHCuEttD_01pXh34/edit
**Included**
1. ajs-quick-reference
Minor changes to remove references to NgModule. Converted sample to standalone.
2. architecture
Migrated the code sample. Made minor changes to remove references to NgModule. I explicitly deprecated the `architecture-module.md` page and removed it from the navigation.
4. deprecations / deprecations-guide
Migrated the code sample which required pulling NgModule and Reactive Forms material into a new `deprecated` folder. Made minor changes to clarify when advice was specific to NgModule (see `loadChildren` in particular).
5. displaying-data
Deleted this `displaying-data` sample entirely as there is no need for a sample app just to display a single, vanilla data binding in the deprecated `zone.md` page. Replaced reference in `zone.md` with an inline code snippet.
10. ngcontainer
Converted the code sample. There is no guide page for this sample. It can be displayed in Stackblitz
**Excluded**
3. cli-builder
Code sample is not an app; nothing to convert.
6-9 - related to getting-started and setup.
Waiting until Angular team is ready to proceed.
11. providers
This is in its own commit and PR 51918 because it may not make sense to convert. See that PR for details.
12. routing-with-urlmatcher
No work needed. Already Standalone.
13 schematics-for-libraries
Non-trivial (see doc notes) and Angular may decide to leave as is. Should have own PR.
14 setup
Non-trivial (see doc notes) and Angular may decide to leave as is. Should have own PR.

Upgrade the existing warning so it now logs an error instead, when an LCP element is determined to not be usings the `priority` attribute. Error is logged, not thrown.

The `NoopAnimationDriver` as static property of `AnimationDriver` prevents it from being removed by tree shaking. This commit deprecates it and exposes the `NoopAnimationDriver` on the public API to replace its usage.
DEPRECATED:
The `AnimationDriver.NOOP` symbol is deprecated, use `NoopAnimationDriver` instead.

The `setupTestingRouter` function is a factory function for creating a
new instance of the `Router`. This function is effectively a no-op.
Developers should use `RouterModule.forRoot` or `provideRouter` in tests
instead.
BREAKING CHANGE: The `setupTestingRouter` function has been removed. Use
`RouterModule.forRoot` or `provideRouter` to setup the `Router` for
tests instead.

Although there are several pages, only `service-worker-getting-started.md` has an example.
That example code was migrated.
Worked around the few references to NgModule.
Other changes as follows:
**Revised "Getting Started"**
The original service worker example page (`service-worker-getting-started.md`) is full of holes! I don’t know how anyone got this working just by following this page
- it doesn’t tell you where to get the example (and it isn’t generated by AIO)
- it doesn’t tell you that ng serve doesn’t support service worker apps
- it mentions http-server in passing but not what that is or where to get it.
- several commands tell you to supply the “project-name” but (a) it doesn’t tell you how to find that name and (b) you never actually have to provide a name at all. That includes on the command that gets http-server going.
**Hid section on `ngsw-config` tool**
Hid the discussion of the `ngsw-config` tool in `service-worker-config.md` because
(a) the command invoke it didn't seem to work and (b) it referenced `<project-name>`
without explaining what that is or where to find it.
Left the hidden text in the page in case someone wants to do something about this.
Meanwhile, you seem to be able to edit the `ngsw-config.json` and then rebuild.
That should suffice.
**Disabled E2E**
The AIO CI will no longer attempt to run the (thin) E2E tests.
These tests could lightly test the app with the dev server but couldn't test the Service Worker aspects; that would require launching the app with something other than `ng serve` and the AIO CI is not set up for that.
The existing tests appeared to pass when run locally with the dev server.
However, only one of them actually ran; test runner reported.
"There were tests whose specified size is too big."
Decided to bypass E2E testing of this project for now.

The `malformedUriErrorHandler` is used as a recovery mechanism for when the `UrlSerializer`
throws an error when parsing a URL string. If custom error handling is
desired for this, it should instead be done inside the
`UrlSerializer.parse` method itself. There's no reason to have an entire
feature option built around what can otherwise just be `try...catch`.
BREAKING CHANGE: `malformedUriErrorHandler` is no longer available in
the `RouterModule.forRoot` options. URL parsing errors should instead be
handled in the `UrlSerializer.parse` method.

upgrade the warning for lazy-loaded lcp images when using NgOptimizedImage to an error
BREAKING CHANGE:
Previously when NgOptimizedImage directive detected that an LCP image is lazy-loaded, a console warning was produced. Now the directive throws an error to make it more discoverable in a console. If you receive this error, refer to this guide for additional information: https://angular.io/guide/image-directive#step-4-mark-images-as-priority

E2E tests passed locally
**Added `readme.md` to the example code**
This explains how to build and run the example for both English and French.
**Archived `i18n-optional-manual-runtime-locale.md`**
I was asked to cut out a substantial swath of this page by reviewer "zip-fa". All that remained was a brief paragraph. I removed the page from the navigation after copying the remaining text to `i18n-optional-import-global-variants.md`. The page is still reachable by 3rd party links.

Heavily reworked with advice from Alan Agius.
FWIW
* `ng test` fails because there are no unit tests
* `yarn e2e` builds but fails - `Unable to start a WebDriver session.`
**Added `readme.md` to sample code**
Makes it easier for the casual downloader to try the example.
**Added `universal-ngmodule`**
The existing ngModule-based doc has a lot of guidance for developers who are still building with NgModule. Given that we are preserving the existing NgModule guidance (with modifications), it seems prudent to preserve the NgModule form of the Universal guidance. So I copied the existing guide and code to `universal-ngmodule` and added it to the left-side navigation under the "NgModules" sub-tree.
Warning: it retains all of the faults of the original guide ... faults that were addressed in the current revision.
