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.
Fixes#58485.

A unit test has been added to check that `EventEmitter` properly completes upon component/directive destrouction when used with `outputToObservable`.
It explains why `destroyRef` has to be injected in `EventEmitter` in the first place.

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.

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.

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
was complete. We should not check SVGs because they are vector-based and can scale
infinitely without losing quality.

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.

Currently during the module pruning stage of the standalone migration we assume that any leftover modules which only have `imports` and `exports` can safely be removed. That can be incorrect for the cases where some parts of the app were converted to standalone outside of the migration.
These changes update the logic so that such modules are replaced with the `exports` which are used within the specific component.

We had some tests that were leaking LViews, because we were testing things like `createComponent`, but not destroying them afterwards. These changes clean up most of them, although there are a handful still left that I didn't have time to fully track down.
PR Close#57546
When we create the LView for a component, we track it in the `TRACKED_LVIEWS` map. It gets untracked when it is destroy, but if it throws during creation, the user won't have access to a `ComponentRef` in order to clean it up.
These changes automatically untrack the related LViews if the component couldn't be created.

This commit reduces the bundle size of `@angular/core` by 19.5 MB by excluding sourcemaps from the schematics.
Since the `esbuild` rule doesn't allow disabling sourcemaps directly, we work around this by setting the sourcemaps to `external`. Afterward, we filter the output to include only the `.js` files.

The `afterRender` infrastructure was first implemented around the idea of
independent, singular hooks. It was later updated to support a spec of
multiple hooks that pass values from one to another as they execute, but the
implementation still worked in terms of singular hooks under the hood. This
creates a number of maintenance issues, and a few bugs. For example, when
one hook fails, further hooks in the pipeline should no longer execute, but
this was hard to ensure under the old design.
This refactoring restructures `afterRender` infrastructure significantly to
introduce the concept of a "sequence", a collection of hooks of different
phases that execute together. Overall, the implementation is simplified
while making it more resilient to issues and future use cases, such as the
upcoming `afterRenderEffect`.
As part of this refactoring, the `internalAfterNextRender` concept is
removed, as well as the unused `queueStateUpdate` concept which used it.

Previously the zoneless scheduler had a concept of whether views needed to
be refreshed or not, based on the notification type that was received. It
tracked this information as a boolean.
This commit refactors things to track dirtiness in `ApplicationRef` itself,
as a `dirtyFlags` field with bits corresponding to either view tree
dirtiness or after-render hooks.

Introduces a simpler, smaller variant of the current `Tsurge` migration
class. The difference is simply that for the migration phase (the third
stage), some migrations do not need a full set of workers re-analyzing
every compilation unit again to compute the "final migration
replacements".
This can be the case, for example, if a migration eagerly computes all
replacements in the analyze stage, visiting every unit, and then after
deriving the global metadata, problematic replacements are simply
filtered (e.g. via some unique IDs again).

This commit simplifies the batching support for the signal input
migration by using the new tsurge framework we've built.
This allows for consistent setup across all possible entry-points and
also simplifies the 1P setup given that we can simply use the Tsurge
macros, instead of having to maintain our own Go-based runner.

* Improves some of the generic assignability for tsurge. Anything is
allowed to be returned from an overridden `prepareProgram` method.
This is useful for the signal input migration.
* Passes the absolute root paths to migrations. This is helpful for the
signal input migration and there is no other way to access it. It's
better to pass specifically, compared to passing the whole unsafe
`ParsedConfiguration` object.

Introduces a migration framework to build batchable migrations that
can run in Large Scale mode against e.g. all of Google, using workers.
This is the original signal input migration infrastructure extracted
into a more generic framework that we can use for writing additional
ones for output, signal queries etc, while making sure those are not
scoped to a single `ts.Program` that limits them to per-directory
execution in very large projects (e.g. G3).
The migration will be updated to use this, and in 1P we will add
helpers to easily integrate such migrations into a Go-based pipeline
runner.
