Angular has long had the ability to use different interpolation delimiters
(by default `{{` and `}}`). This concept was copied over from AngularJS,
where AngularJS syntax is included in HTML sent over the network to the
browser. Occasionally developers would use SSR frameworks which _also_ have
interpolation syntaxes of their own, so there was a need to change the
delimiters used by AngularJS to avoid conflicts.
Since Angular templates are always processed by our compiler and the
interpolation characters are never processed by other systems first, this
option is vestigial in Angular and only increases the complexity of our
parser.
DEPRECATED: `@Component.interpolation` is deprecated. Use Angular's
delimiters instead.

This reuses information already recorded during hydration to
remove jsaction attributes to also stash event handlers. This avoids
a tree walk and looku.

The first test asserts that bubbling does not work right now.
The second asserts that stopPropagation works, which should pass when test #1 passes too.
The third test asserts properties about the events passed to the event handler.
THe fourth test asserts that mouse events do not translate to jsaction nor help emit the jsaction binary. This required a change in code to make this pass.

Currently the variable optimization phase happens somewhat late in the process which is okay since the variables are generally static (e.g. `reference()` instruction calls). In some upcoming work we'll have variables that consume slots and require `advance` instructions. To allow for them to be optimized correctly, we need to move the variable optimization phase earlier, at least before we allocate the slots.

This commit adds a feature that is useful for determining if an
application is zoneless-ready. The way this works is generally only
useful right now when zoneless is enabled. Some version of this may be useful in
the future as a general configuration option to change detection to make
`checkNoChanges` pass always exhaustive as an opt-in to address #45612.
Because this is an experimental, debug-only feature, it is okay to merge
during the RC period.

This behavior is now implemented by calling `dispatch` whether or not
the `action` is populated. The `Dispatcher` then does global dispatch
and early returns if there's no action.

This commit updates the implementation of the `addEventListener` patcher.
We're currently creating an abort event listener on the signal (when it's provided)
and never remove it. The abort event listener creates a closure which captures `task`
(tasks capture zones and other stuff too) and prevent `task`, zones and signals from
being garbage collected.
We now store the function which removes the abort event listener when the actual event
listener is being removed. The function is stored on task data since task data is already
being used to store different types of information that's necessary to be shared between
`addEventListener` and `removeEventListener`.

Related to #51131, this change ensures that the router navigation exits

Prior to this change, `NgZone` was provided by default in TestBed in a
location that would override anything configured in
`TestBed.initTestEnvironment`. This change moves the default `NgZone`
provider to the `RootScopeModule` and these providers can be overridden
by the ones in `additionalModuleTypes`, which are assigned from the
first argument of `initTestEnvironment`. This makes it possible to
configure Zone globally for all tests as opposed to needing to repeat it
in `configureTestingModule` of each suite.

Closure compiler optimizations in g3 require `.then` to be present for a dynamic import (or an import should be `await`ed) to detect the set of imported symbols. Currently, the `.then` is located at a later stage in the file, which confuses static code analysis. This change adds the `.then((m) => m)` workaround to satisfy Closure compiler constraints.

This commit addresses dependency injection defects when using the `withFetch` API. Formerly, utilizing `withFetch` led to the automatic setting of `HttpBackend` to `FetchBackend`, which proved problematic in certain scenarios. Notably, conflicts arose when integrating `withRequestsMadeViaParent` and manually overriding tokens, as observed in instances like `InMemoryWebApiModule`.

This commit handles two cases that were breaking applications when using the new migration:
- tests using `HttpClientModule` in `TestBed.configureTestingModule` were broken as the import was removed, but the module is still present in the test configuration. It now properly adds `provideHttpClient(withInterceptorsFromDi())` and related imports to the test.
- tests using `HttpClientTestingModule` were migrated to use `provideHttpClient(withInterceptorsFromDi())` but the necessary imports were not added. They are now added by the migration.

This commit updates the list of Node.js `fs` APIs to be patched because
they haven't been updated for a long time. It adds `opendir,lutimes,writev`.
For example, the `opendir` method was added to Node.js in version 12.12.0 in
2019, causing some of the APIs to potentially be always called within the
`<root>` context.
**Note:** There are missing unit tests for these changes because in unit tests,
`fs` is patched by Bazel's Node.js rules and its `node_patches.cjs`. However,
the APIs are successfully patched in the real production code and are called
with the correct context.

Rather than attempting to use the native timing functions, this commit
simplifies the logic significantly by using the global timer functions
as they are, either patched or unpatched. When Zone is defined, we run
the timers in the root zone. This has more predictable behavior and
timing than (a) using both patched and unpatched versions of timers in
different places (b) trying to get an unpatched timer and failing due to
environment specifics and patches that aren't ZoneJS.

Fixes that we didn't have the MathML elements in the schema. Note that we can't discover which tag names are available by looking at globally-available classes, because all MathML elements are `MathMLElement` rather than something like `SVGCircleElement`. As such, I ended up having to hardcode the currently-available tags.

This reverts commit 7e89753eef.
Running render hooks inside the zone is specifically problematic for
`afterRender` hooks. If the callback has async task, it would cause an
infinite change detection. In addition, updating state in render hooks
is generally discourages and certainly should update state in a way that
notifies Angular of the change (either via signal or with `markForCheck`) rather
than relying on ZoneJS to pick it up (which would only work if the
change is done inside an async task).
PR Close#55624
This commit fixes an error in the looping logic of `ApplicationRef.tick`
when the tick skips straight to render hooks. In this case, if a render
hook makes a state update that requires a view refresh, we would never
actually refresh the view and just loop until we hit the loop limit.
PR Close#55623
Currently we add global extra imports to all the files in the compilation unit. However not all the files need extra imports. For example non-Angular files definitely do not need such extra imports, and in some cases these extra imports causes problems as the file is meant to be run the Node but it has Angular dependencies which are not compatible with Node. This change tries to limit extra import generation to a subset of files. Wit hthis change we create extra imports only for the files that contain at least one component whose NgModule is in a different file. This is because all other files do not need extra imports since they are either not Angular files or they already have all the imports that the components need.
