This commit prevents doubling change detections when the zoneless
scheduler is notified first, followed by the zone becomeing unstable
(effectively "scheduling" zone-based change detection). When run
coalescing is enabled, this would otherwise result in the zoneless
scheduler running change detection first and then change detection
running again because of the run coalescing since both scheduler use the
same timing function (and then it would be FIFO).

In Angular today, a bound listener automatically marks the view for
check. When using ZoneJS, these listeners are most often executed in the
Angular Zone as well, so synchronization (`ApplicationRef.tick`) will
eventually happen. _However_, developers can opt out of zone-patching
for events in several ways, and often do this for very frequent
listeners like `mousemove`, `resize`, and `scroll`. We do not want to
break existing expectations that these are now "safe" events to have
listeners for by automatically scheduling change detection regardless of
whether the listener executed inside or outside the Angular zone.
In contrast, in order for developers to more easily transition to zoneless,
we need to be able to ensure that components which are using `OnPush`
are, for the most part, compatible with zoneless as well. Because listeners
automatically mark the component for check, developers using `OnPush`
did not/do not need to also call `ChangeDetectorRef.markForCheck` or a
similar API. Unfortunately, this means that we need to consider the
listener callbacks as a notification to schedule a `tick` when Zoneless
is enabled. In the future, we would like to have an opt-out for this
(i.e. signal components) since it's not really how we _want_ things to work.

This commit modifies the setup of the injector profiler to occur solely when the application is running in a browser context. This adjustment is made because the injector profile serves no purpose when the application is running on the server.

The timing of render hook execution is almost entirely identical to
`ngZone.onMicrotaskEmpty`. Developers working towards zoneless
compatibility will need to migrate `onMicrotaskEmpty` calls to use
`afterNextRender`/`afterRender` instead. This, however, would lead to
confusing issues if there are promises in the callbacks because
`onMicrotaskEmpty` emits inside the Angular zone while render hooks
execute outside today. This is problematic because it's not documented
and does not produce any notification or error message when async work
is done inside the hooks that requires change detection. Instead, change detection
simply does not run, and this behavior has proven to be surprising to
developers who are used to ZoneJS change detection behavior.

Currently fallback content for `ng-content` gets declared and rendered out in one go. This breaks down if multiple instances of the same component are used where one doesn't render the fallback content while the other one does, because the `TNode` for the content has to be created during the first creation pass.
These changes resolve the issue by always _declaring_ the template, but only rendering it if the slot is empty.
Fixes#55466.

The new ExperimentalPendingTasks API lets developers to add and remove
tasks that control applications stability: a pending task prevents
application from being stable.
This API is important for all the use-cases that depend on the concept
of stability and SSR serialization is a notable example.

This change ensures that `ApplicationRef.tick` flushes animations by
calling `rendererFactory2.end`. This might not have happened before if
there were no views that needed to be refreshed.
This is also likely to fix a potential regression caused by #53718 even
in zone apps where animations don't get flushed when no views attached
to ApplicationRef are dirty.

This commit fixes an issue where event contract init script was injected into the page before the inlined event dispatch script. That resulted in runtime exceptions, since event contract relies on some code being present on a page already.

This commit updates the logic to take into account a situation when Event Replay feature is enabled (using `withEventReplay()` method), but there were no events configured in an application. In this case, there is no need to setup an event dispatcher and trigger event replay.

This commit updates Terser config to disable property renaming for the event delegation script (that we later inline into the HTML during SSR). The problem is that event dispatcher relies on some functions on the EventContract class to have original names after after minification, we loose an ability to call those functions.
