Currently the HTTP status code and headers are only included if the request succeeded. Given status codes convey more information in case of a request error vs. success, this makes it more useful than inspecting what is contained in `.error()`.

This commit updates the `HttpClient` internals to use the public
`PendingTasks` API which delays stability until the next
`ApplicationRef.tick` instead of causing the application to become
stable synchronously. This is helpful to resolve unexpected issues where
computations happen as follow-up work to the value coming out of the
response.

In this commit, we unsubscribe the `hasPendingTasks` subject to remove all active observers and enable granular garbage collection, as users may forget to unsubscribe manually when subscribing to `isStable`.

The non reactive usage ``httpResource(\`http://test/${myId()}\`` gave the false impression that it was reactive when the signal was invoked. We prevent any possibility of oversight by removing the non reactive signature.

Moves the `DOCUMENT` token from `common` into `core` since it's relevant for lots of SSR use cases and users shouldn't have to install `common` for it. The token is still exported through `common` for backwards compatibility.

Note: This is not a deprecation of structural directives, this only about `ngIf`/`ngFor`/`ngSwitch`.
DEPRECATED: `ngIf`/`ngFor`/`ngSwitch` are deprecated. Use the control flow blocks instead (`@for`/`@if`/`@switch`).

Node.js v18 will reach End-of-Life on April 30, 2025, and will no longer be supported in Angular v20.
Node.js Release Schedule: https://github.com/nodejs/release#release-schedule
BREAKING CHANGE:
- Angular no longer supports Node.js v18.
- Node.js versions 22.0 to 22.10 are also no longer supported.
Before upgrading to Angular v20, ensure the Node.js version is at least 20.11.1.

`TestBed.get` isn't type safe and has been deprecated for several years now. These changes remove it from the public API and a follow-up change will add an automated migration to `TestBed.inject`.
BREAKING CHANGE:
* `TestBed.get` has been removed. Use `TestBed.inject` instead.

Usage of the `fast-glob` package has been replaced with the `tinyglobby` package. The change reduces the number of transitive dependencies related to these packages from 17 to 2 while also maintaining equivalent functionality. This was also changed in the Angular CLI packages.

`AsyncPipe` would previously promise rejections unhandled and
subscription errors uncaught. This is more or less fine in a Zone-based
application because errors inside the Angular Zone are caught be the
Zone's error trap and reported to `ErrorHandler`. However, in zoneless
applications, these errors are never caught or reported by the FW and
can reach the node process in SSR and cause it to shut down.
BREAKING CHANGE: `AsyncPipe` now directly catches unhandled errors in
subscriptions and promises and reports them to the application's
`ErrorHandler`. For Zone-based applications, these errors would have
been caught by ZoneJS and reported to `ErrorHandler` so the result is
generally the same. The change to the exact mechanism for reporting can
result in differences in test environments that will require test
updates.

`HttpClient` has a lot of overloads to achieve proper type checking, however each overload is also very long which makes it hard to read on adev. These changes replace the object literal types with `Record` to make them a bit more concise.

Adjusts the date pipe and formatDate function to detect suspicious usages of the week-numbering year formatter without including the week number, as this is often confused for the calendar year and likely to result in incorrect results near New Years, meaning that those issues aren't typically caught during development. This commit starts throwing a development-only error to reveal this issue right away.
BREAKING CHANGE:
Using the `Y` formatter (week-numbering year) without also including `w` (week number) is now detected as suspicious date pattern, as `y` is typically intended.

This moves the `FakeNavigation` implementation to the primitives folder
so its implementation can be shared with Wiz. This class was initially
copied directly from the Wiz implementation, with some small modifications.
There will still need to be some work done to align the implementations
and fix anything internally that needs adjusting.

The refactored version improves the original code by removing the `supports` method from the prototype and inlining the logic directly into the `transform` method. This reduces indirection and simplifies the class, especially since `supports` is not reused elsewhere. ESBuild can directly inline the condition into the `if` statement by removing the variable: `if (!("string" == typeof e || Array.isArray(e))) throw i(s, e);`.

The new version of the function is smaller, eliminating extra bytes. The refactor improves both code size and readability while optimizing the implementation. Benchmark results for the old and new implementations are as follows:
```
stripTrailingSlash_old x 15,446,602 ops/sec ±0.89% (66 runs sampled)
stripTrailingSlash_new x 19,694,523 ops/sec ±1.10% (61 runs sampled)
```
Thus, the new implementation is both smaller and faster.

In this commit, the `urlChanges` subject is completed to release all active observers when the root scope is destroyed. Previously, subscribing to the `urlChanges` subject caused the subscriber to capture `this`, resulting in a memory leak after the root scope was destroyed.

`httpResource` is a new frontend to the `HttpClient` infrastructure. It
declares a dependency on an HTTP endpoint. The request to be made can be
reactive, updating in response to signals for the URL, method, or otherwise.
The response is returned as an instance of `HttpResource`, a
`WritableResource` with some additional signals which represent parts of the
HTTP response metadata (status, headers, etc).

The new version is 2x smaller in the reduced code size; as thus this eliminates extra bytes. Refactors `joinWithSlash` function to reduce code size and improve readability. Added checks to handle leading and trailing slashes more concisely and provided comments for clarity.

In this commit, we remove the separate `a === undefined` and `a === null` checks and replace them with `a == null`. Using `a == null` is better and more concise because it checks for both `null` and `undefined` in a single operation. The loose equality `==` is specifically designed to treat `null` and `undefined` as equivalent. This change only reduces some bytes in the code and simplifies it, with no performance impact, as modern JavaScript engines handle `a == null` efficiently. Additionally, comments have been added for clarification.

This commit introduces an update to the official recommendations when it comes to class & styles bindings.
`[class]` & `[style]` bindings are now recommended for basic uses cases.
`[ngClass]` and `[ngStyle]` allow more advanced bindings (like space separated keys) or keys with units (for `ngStyle`) which are not supported by the native bindings. They still require the dedicated directives.

Prior to this commit, the `this.lcpObserver?.updateImage` expression was still preserved in the production code because it wasn't wrapped with `ngDevMode`. The observer is injected only in development mode. Additionally, we moved the logic from `ngOnDestroy` to avoid having an empty method in production.
