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
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.
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.

Nothing of concern arose during the time this feature was in the
experimental phase. There are no plans to change the shape of the API.
This change also updates the route animations documentation to use the
view transitions feature instead of the old and difficult to follow
guide that used the animations package. The content was taken from the
blog post: https://blog.angular.io/check-out-angulars-support-for-the-view-transitions-api-3937376cfc19

Before this commit, `@let` decleration with an array where mistaken for a component in the lView and throwing an unexpected error.
This commit fixes this.

Currently several parsing errors in the new control flow (e.g. missing `track` expression) produce errors whose span targets the entire block. This can be really noisy in the IDE where the error can span many lines in the template.
These changes switch to highlighting just the start of the block.

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.
Fixes#51420.

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.
