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`).

`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.

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.

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.

Note: this enums are not a part of the public API.
Prior to this commit, the compiler produced:
```js
var DateType;
(function (DateType) {
DateType[DateType["FullYear"] = 0] = "FullYear";
DateType[DateType["Month"] = 1] = "Month";
DateType[DateType["Date"] = 2] = "Date";
DateType[DateType["Hours"] = 3] = "Hours";
DateType[DateType["Minutes"] = 4] = "Minutes";
DateType[DateType["Seconds"] = 5] = "Seconds";
DateType[DateType["FractionalSeconds"] = 6] = "FractionalSeconds";
DateType[DateType["Day"] = 7] = "Day";
})(DateType || (DateType = {}));

With these changes, we allow objects to be dropped entirely and inlined.

This commit removes a custom `whenStable` util in favor of standard `ApplicationRef.whenStable` API.
There is also an important different between the custom `whenStable` function and `ApplicationRef.whenStable` implementation: the `whenStable` was caching the "stable" promise on per-ApplicationRef basis, which resulted in unexpected behavior with zoneless, when some code ended up getting a stale resolved promise, when an application was not stable yet, this causing order of operations issues. This commit also has an extra test that covers that case.

The keyvalue pipe sorts the entries of the input by key. This has been the subject of debate in the past (https://github.com/angular/angular/issues/42490). The core of the discussions is that it is often desirable (and perhaps expected) that they natural ordering of the input is respected. There are at least two workarounds to restore natural ordering, such as a `compareFn` that simply returns `1` or a custom pipe. However, both of these require code for pipe consumers to maintain or copy around to many places.
Allowing `null` as `compareFn` and treating it as "natural order" is fairly simple to understand, backward compatible and was suggested a few times on https://github.com/angular/angular/issues/42490 where it seemed to be received well. Using `null` is also possible in templates without any component code changes.

With this commit, we're now able to perform checks even when the image has already
been loaded (e.g., from the browser cache), and its `load` event would never be triggered.
We use the [complete](https://html.spec.whatwg.org/#dom-img-complete) property, as specified,
which indicates that the image state is fully available when the user agent has retrieved all
the image data. This approach effectively triggers checks, as we no longer solely rely on the
`load` event and consider that the image may already be loaded.
This will not remove the placeholder until the `load` event fires (and it won't fire if the
image is already "there").
This prevents memory leaks in development mode, as `load` and `error` event listeners are
still attached to the image element.
