Add an `AbortSignal` parameter to `Debouncer`. Implementations may
choose to accept this parameter to be informed when a debounced
operation is aborted. This may be useful for canceling pending timers or
avoiding unnecessary work.

This commit introduces a new guide for migrating existing Angular projects from Karma/Jasmine to Vitest.
The guide covers:
- Manual steps for installing dependencies and updating `angular.json`.
- Handling custom `karma.conf.js` configurations.
- Removing Karma-related files and packages.
- Configuring browser mode for Vitest.
- Details on the `refactor-jasmine-vitest` schematic for automated test refactoring.
The guide also clarifies that while Vitest is the default for new projects, migration for existing projects is experimental. It emphasizes reviewing changes and provides guidance on adapting custom Karma configurations to Vitest.
Renames `experimental-unit-test.md` to `migrating-to-vitest.md` and updates `sub-navigation-data.ts` accordingly.

Reworks the way we approach type checking of signal forms to be closer to the behavior at runtime. There are a couple of scenarios that we handle:
1. For native controls, we now produce simplified type checking code that looks as follows:
```
var t1 = null! as number | string; // Type depends on the input `type`.
t1 = someField().value();
```
2. For custom controls we generate bindings to the individual inputs, rather than checking conformance against `FormValueControl`/`FormCheckboxControl`. This is closer to the behavior at runtime and it allows us to handle generic directives properly.

This change configures pnpm to allow any version of `@angular/*` packages to satisfy peer dependencies. This is necessary because `@angular/*` packages are managed within this monorepo, and this rule prevents issues with peer dependency resolution when different versions might be present during development or testing.

:nth-child() (and its siblings) support complex expressions, e.g.
`:nth-child(2n of :is(.foo, .bar))`. Previously we'd choke because of
the `:is()`. Now, we reuse the `_parenSuffix` subexpression to match
nested parentheses the same way we do for :host() and :host-context().
Note that we only support 3 levels of nesting, so a selector like
`:nth-child(n of :is(:has(:not(.foo))))` will still break.
I'll say yet again that we really should add a proper parser so we stop
getting bug reports like this :)

Refactor to use async/await for clearer asynchronous operations and enhanced error handling.
Simplify resource caching and streamline the resolution of component templates and styles.
Update in the router to align with the new async resource resolution.

The `debounce()` rule allows developers to control when changes to a
form control are synchronized to the form model.
This feature necessitated some changes to `FieldState`:
* `controlValue` is a new signal property that represents the current
value of a form field as it appears in its corresponding control.
* `value` conceptually remains unchanged; however, its value may lag
behind that of `controlValue` if a `debounce()` rule is applied.
The `debounce()` rule essentially manages when changes to `controlValue` are
synchronized to `value`. The intent is that an expensive or slow
validation rule can react to the debounced `value`, rather than a more
frequently changing `controlValue`.
Directly updating `value` immediately updates `controlValue`, and cancels any
pending debounced updates.
When multiple `debounce()` rules are applied to the same field, the last
currently active rule is used to debounce an update. These rules are
applied to child fields as well, unless they override them with their
own rule.

This removes the need to specify type arguments for
`reducedMetadataKey()` when the value returned from the `getIntial`
callback is a subtype of the accumulated type.

The flag `skipFormatting` got renamed to `ngSkipFormatting` during review of https://github.com/angular/angular/pull/64000, but a couple usages got missed, causing some unfortunate UI recursion.
(cherry picked from commit 490435bf76)
The `fullInheritane` flag from the metadata and the `CopyDefinitionFeature` that it controls appear to no longer be used since `fullInheritance` is always false. The feature appears to have been there to support ngcc which was removed some time ago.

Prior to this commit, attempting to resolve a `ChangeDetectorRef` after views or app have been destroyed would result in an error. In this commit, we clean up listeners once the view is destroyed, before the placeholder loads or fails to load.

Wraps InjectionToken names with `typeof ngDevMode !== 'undefined' && ngDevMode`
checks to enable tree-shaking of descriptive token names in production builds.
This ensures debug-only strings are removed from production bundles, reducing size.
Also removes unused imports found during refactor.
(cherry picked from commit b0b834d7f1)
Annotate the `new Version(...)` call with `/* @__PURE__ */` to signal to optimizers that the constructor is side-effect free.
Without this hint, bundlers such as Terser or ESBuild may conservatively retain the `VERSION` instantiation even when unused. With the annotation, the constant can be tree-shaken away in production builds if not referenced, reducing bundle size.
