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.

Prior to this change, a scheduled root effect, even if destroyed instantly, would still run at least once.
This commit fixes this.

When we replace a component during HMR, we clear it from the cache of the renderer factory, however when using animations, there's an animation-specific renderer factory that wraps the base DOM one and was preventing the cache from being cleared.
These changes rework the logic that clear the cache to go through a method so we can forward the call to the delegated factory.

This commit updates the code of the incremental hydration feature to make the `DeferBlockRegistry` class tree-shakable. The class is only needed for hydration cases and it should not be included into client bundles for client-only apps.

This commit adds the `ngServerMode` as global, which allows for the tree-shaking of server-only code from the bundles. When this flag is unset at runtime, server-specific code will be excluded by Closure, optimizing bundle size.
**Internal Angular Flag:** This is an internal Angular flag (not a public API), avoid relying on it in application code.
PR Close#58386
When setting `"useDefineForClassFields": false`, static fields are compiled within a block that relies on the `this` context. This output makes it more difficult for bundlers to treeshake and eliminate unused code.

For scroll-blocking events like 'touchstart', 'touchmove', 'wheel' and 'mousewheel',
if passive option is not specified when adding the event listener, browser may give
a violation warning.
This PR allows us to set the passive option when calling event lib's addEvent().

By removing the standalone feature, we reduce the amount of code generated for components but at the cost of including the `StandaloneService` in the main bundle even if no standalone components are included in it.
PR Close#58288
The runtime default is now `standalone: true`.
`ɵɵdefineComponent`, `ɵɵdefineDirective` and `ɵɵdefinePipe` now set `standalone` as `true` by default in the definitions.

This commit adds an operator to help rxjs observables important for rendering
keep the application unstable (and prevent serialization) until there is
an event (observable emits, completes, or errors, or the subscription is
unsubscribed). This helps with SSR for zoneless and also helps for when
operations are intentionally executed outside the Angular Zone but are
still important for SSR (i.e. angularfire and the zoneWrap helper hacks).

Angular DevTools is working on developing signal debugging support. This commit is a step in the direction of making available debug information to the framework that will allow Angular DevTools to provide users with more accurate information regarding the usage of signals in their applications.
Follow up PRs that will use this arg will:
- Develop a typescript transform that will detect usages of signal functions and attempt to add a debugName without the user needing to specify one directly
- Develop debug APIs for discovering signal graphs within Angular applications (using debugName as a way to label nodes on the graph)

This commit adds an `applicationMaxAge` to the service worker configuration. When set, it will only assign a cached version to clients within the `maxAge`. Afterwards, it will ignored any expired application versions and fetch exclusively from the network. The default is `undefined`, for which the behaviour is the same as it currently is.

Implementations of two rxjs-interop APIs which produce `Resource`s from
RxJS Observables. `rxResource()` is a flavor of `resource()` which uses a
projection to an `Observable` as its loader (like `switchMap`).
PR Close#58255
Implement a new experimental API, called `resource()`. Resources are
asynchronous dependencies that are managed and delivered through the signal
graph. Resources are defined by their reactive request function and their
asynchronous loader, which retrieves the value of the resource for a given
request value. For example, a "current user" resource may retrieve data for
the current user, where the request function derives the API call to make
from a signal of the current user id.
Resources are represented by the `Resource<T>` type, which includes signals
for the resource's current value as well as its state. `WritableResource<T>`
extends that type to allow for local mutations of the resource through its
`value` signal (which is therefore two-way bindable).

This change introduces the new reactive primitive: linkedSignal.
A linkedSignal represents state (hence the signal in the name)
that is reset based on the provided computation. Conceptually
it is a state that is maintained / valid only in the context of
another source signal (context is deteremined by a computation).

This commit exposes the new producerMarkClean utility that
makes it possible to mark a reactive node as clean following
changes to the node's value. In practice it resets the dirty
flag and all other internal flags as need. Prior to this change
the cleanup code was duplicated.
The new utility will be used in the linkedSignal implementation.

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.
