This commit introduces a number of changes to the server bootstrapping process to make it more robust and less error-prone, especially for concurrent requests.
Previously, the server rendering process relied on a module-level global platform injector. This could lead to issues in server-side rendering environments where multiple requests are processed concurrently, as they could inadvertently share or overwrite the global injector state.
The new approach introduces a `BootstrapContext` that is passed to the `bootstrapApplication` function. This context provides a platform reference that is scoped to the individual request, ensuring that each server-side render has an isolated platform injector. This prevents state leakage between concurrent requests and makes the overall process more reliable.
BREAKING CHANGE:
The server-side bootstrapping process has been changed to eliminate the reliance on a global platform injector.
Before:
```ts
const bootstrap = () => bootstrapApplication(AppComponent, config);
```
After:
```ts
const bootstrap = (context: BootstrapContext) =>
bootstrapApplication(AppComponent, config, context);
```
A schematic is provided to automatically update `main.server.ts` files to pass the `BootstrapContext` to the `bootstrapApplication` call.
In addition, `getPlatform()` and `destroyPlatform()` will now return `null` and be a no-op respectively when running in a server environment.

While having both `HttpClientModule` & `HttpClientTestingModule` serves no real purpose (`HttpClientTestingModule` imports `HttpClientModule`), some code bases can have those 2 together and the migration can be quite breaking.

When we check for duplicates in dev mode, we end up stringifying an `LView` even if we don't report an error. This can be expensive in large views.
These changes work around the issue by only generating the string when we have an error to throw.
Fixes#58509.

When the compiler generates the `HostDirectivesFeature`, it generates either an eager call (`ɵɵHostDirectivesFeature([])`) or a lazy call (`ɵɵHostDirectivesFeature(() => [])`. The lazy call is necessary when there are forward references within the `hostDirectives` array. Currently we resolve the lazy variant when the component definition is created which has been enough for most cases, however if the host is injected by one of its host directives, we can run into a reference error because DI is synchronous and the host's class hasn't been defined yet.
These changes resolve the issue by pushing the lazy resolution later during directive matching when all classes are guanrateed to exist.

named as the values of the `TaskType` type.
The Closure Compiler used at Google has a property renaming optimization
that can change the property names when minifying code. Having the
correct type helps the TSJS team that develops a tool to identfy
property renaming issues directly in TypeScript.

parse constructions like `:where(:host-context(.foo))` correctly
revert logic which lead to decreased specificity if `:where` was applied
to another selector, for example `div` is transformed to `div[contenta]`
with specificity of (0,1,1) so `div:where(.foo)` should not decrease it
leading to `div[contenta]:where(.foo)` with the same specificity (0,1,1)
instead of `div:where(.foo[contenta])` with specificity equal to (0,0,1)

The `bootstrap()` phase might fail e.g. due to an rejected promise in some `APP_INIIALIZER`.
If `PlatformRef` is not destroyed, then the main app's injector is not destroyed and therefore `ngOnDestroy` hooks of singleton services is not called on the end (failure) of SSR.
This could lead to possible memory leaks in custom SSR apps, if their singleton services' `ngOnDestroy` hooks contained an important teardown logic (e.g. unsubscribing from RxJS observable).
Note: I needed to fix by the way another thing too: now we destroy `moduleRef` when `platformInjector` is destroyed - by setting a `PLATFORM_DESTROY_LISTENER`

We stop tracking `afterRender` hooks as soon as they execute, but their on destroy callbacks stay registered until either the injector is destroyed or the user calls `destroy` manually. This was leading to memory leaks in the `@defer` triggers based on top of `afterRender` when placed inside long-lived views, because the callback would execute, but its destroy logic was waiting for the view to be destroyed.
These changes resolve the issue by destroying the `AfterRenderRef` once it is executed.

This commit updates the `fetch` patch for zone.js. Currently, we're attaching an
`abort` event listener on the signal (when it's provided) and never removing it.
We should be good citizens and remove event listeners whenever objects need to be
properly collected. In Firefox, when saving a heap snapshot and running it through
`fxsnapshot`, querying `AbortSignal` will print a so-called "CaptureMap" with a list
of "lambdas," indicating that the signal is not garbage collected because of the event
listener lambda function.

Currently we don't defer any symbols that have references outside of the `import` statement and the `imports` array. This is a bit too aggressive, because it's possible that the symbol is only used for types (e.g. `viewChild<SomeCmp>('ref')`) which will be stripped when emitting to JS.
These changes expand the logic so that references inside type nodes aren't considered.
**Note:** one special case is when the symbol used in constructor-based DI (e.g. `constructor(someCmp: SomeCmp)`, because these constructors will be compiled to `directiveInject` calls. We don't need to worry about them, because the compiler introduces an addition `import * as i1 from './some-cmp';` import that it uses to refer to the symbol.
Fixes#55991.

I’ve noticed that there was a loop inside a loop. Since we’re already iterating through
`images` using `forEach`, it was running a `for` loop through `images` again. This was
probably a mistake made when the functionality was initially added. The test actually
verified that `logs.length` is `1`, but in the real environment, it logs twice
(which is quite obvious due to the code).
I’ve also added the missing file to the Bazel target.

This commit removes event listeners from the `script` element once loading is
complete. If the element is not garbage collected properly, in Firefox, the script
element still appears in the memory tree view, captured by
`__zone_symbol__loadfalse -> HTMLScriptElement -> GC Roots`. We should always be good
citizens and clean up event listeners when we no longer need them, as browser's garbage
collectors work differently. Calling `remove()` on the node doesn't guarantee that the
node can be collected.

Prior to this commit, the `ImagePerformanceWarning` class was checking all `img`
elements in the DOM to determine whether they were oversized after the DOM loading

Adds a `manualCleanup` flag to `afterRender` and `afterNextRender`, similarly to `effect`. The reason is that currently if the hook is created outside of an injection context, it requires an injector to be passed in. In some cases that injector might be an injector that is never destroyed (e.g. `EnvironmentInjector`) which can give a false sense of security users thinking that the hook will be cleaned up automatically. We fell into this in the CDK which caused a memory leak (see https://github.com/angular/components/pull/29709). With the `manualCleanup` option users explicitly opt into cleaning the hook up themselves.

`@angular/upgrade` writes to inputs when downgrading an Angular 2+ component
into an Angular.JS adapter. Previously, it wrote directly to the input
property, which isn't compatible with input signals. It also handles
`ngOnChanges` directly.
The correct way to support input signals would be to refactor upgrade to use
`ComponentRef.setInput`, which also handles `ngOnChanges` internally.
However, this refactoring might be more breaking since it would change the
timing of certain operations. Instead, this commit updates the code to
recognize `InputSignal` and write it through the `InputSignalNode`. This
avoids the above breaking changes for now, until a bigger refactoring can be
tested.
Fixes#56860.

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.
