Lock file maintenance updated Terser, which impacts the bundle
optimizations being tested via the symbol golden tests.
There was a small noticable change in the symbol golden where
`withDomHydration` is now preserved, and the underlying function
that was previously detected is gone. Seemingly Terser now inlines
this function and had to preserve `withDomHydration` as the entry point.

Rather than leaving the timers around as no-ops, this commit updates the
logic to also attempt to clear or cancel the timers. This is helpful for
the eventual goal of running the scheduler in the `fakeAsync` zone (if
the test is running in `fakeAsync`) rather than scheduling in the root
zone and making it impossible to flush.

This creates a private option that can be used internally while we
migrate this to the default and only behavior. ~200 tests in TGP have errors
that are being swallowed (console.log) and not causing the test to fail.
We can first explicitly opt those out, flip the default internally, then
"fix" them by adding expect...toThrow.

To increase the ease of development we are moving @angular/docs into the adev directory within this repo. While
we are doing this to improve our development experience in the short term, efforts are also in place
to maintain a division between this @angular/docs (shared) code and adev itself, so that it can be extracted
back out in the future when components is ready to leverage it as well.

The behavior of `ComponentFixture` for zoneless tests was decided somewhat through guesswork, trial, and error. In addition, working on the zoneless fixture revealed oddities in the behavior of the zone-based fixture, or behaviors that we felt were counterintuitive. The most consequential difference is how change detection works: `detectChanges` goes through ApplicationRef.tick in zoneless while it is `changeDetectorRef.detectChanges` in the zone fixture.
We felt that running change detection through `ApplicationRef.tick` was important for several reasons:
* Aligning application behavior more closely with the test behavior (almost all views are attached to application ref in reality)
* Ensuring that afterRender* hooks are executed when calling `fixture.detectChanges`
* Ensuring that the change detection runs again if render hooks update state
This change, however, has some noticeable consequences that will break some tests, mostly around how errors are handled. `ApplicationRef.tick` catches errors that happen during change detection and reports them to the ErrorHandler from DI. The default error handler only logs the error to the console. This will break tests which have `expect(() => fixture.detectChanges()).toThrow()`. In addition, it allows tests to pass when there are real errors encountered during change detection.
This change ensures that errors from `ApplicationRef.tick` are rethrown
and will fail the test. We should also do a follow-up investigation to
determine whether we can/should also do this for the zone-based
`ComponentFixture`.

Currently we use some short variable names like `t` and `r` in the generated factory functions. They can conflict with local symbols with the same names, if they're used for DI.
These changes add a `ɵ` to the generated variables to reduce the chance of conflicts.

This reverts commit 66ffeca2de.
It looks like nuxt encountered the same issue with scrolling when
waiting for Vue's `nextTick`, which is a microtask. This would have
similar timing to ZoneJS's rendering in the microtask queue. This
reverts to a `setTimeout` alone, though recreates the problem in #53985.
This was also mentioned in one of the comments in the Nuxt issue and the
solution would be `rAF`.
In order to address #53985, we'd likely want to use the `race(rAF, setTimeout)`
that we use in the zoneless and coalescing schedulers. This would have effectively the same timing as
the `afterNextRender` implementation here with zoneless, but quite
different timing to `afterNextRender` with ZoneJS.

Some Angular template instructions that follow each other may be chained
together in a single expressions statement, containing a deeply nested
AST of call expressions. The number of chained instructions wasn't previously
limited, so this could result in very deep ASTs that cause stack overflow
errors during TypeScript emit.
This commit introduces a limit to the number of chained instructions to
avoid these problems.

The `Timeout` object in Node.js has a `refresh` method, used to restart `setTimeout`/`setInterval` timers. Before this commit, `Timeout.refresh` was not handled, leading to memory leaks when using `fetch` in Node.js. This issue arose because `undici` (the Node.js fetch implementation) uses a refreshed `setTimeout` for cleanup operations.
For reference, see: https://github.com/nodejs/undici/blob/1dff4fd9b1b2cee97c5f8cf44041521a62d3f133/lib/util/timers.js#L45Fixes: #56586

Fixes that the runtime implementation of `ɵɵngDeclareDirective` was interpreting the `hostDirectives` mapping incorrectly.

In #56358 we removed most of the places that untag the references to typecheck files, because it was causing the compiler to throw error when it produces diagnostics. This appears to have caused a regression in TS 5.4 which now emits the synthetic references.

This is the first step towards combining `EarlyEventContract` and `EventContract`. It contains a few refactors, such as making names more consistent.
The goal of this refactor is to remove the `EarlyEventContract` class altogether, as well as `EventContract`.
To install the early event contract with the default events in early script tag, users will call:
`bootstrapGlobalEarlyEventContract()`
And for boostraping:
`registerGlobalDispatcher(dispatcher)`

When we process `@if` and `@for` blocks, we create a scope around their expressions in order to encapsulate the aliases to them. The problem is that this doesn't represent the actual structure since the expression is part of the outer scope. This surfaces by not raising the "used before declared" diagnostic for `@let` declarations.
These changes resolve the issue by processing the expression as a part of the parent scope.
