Replace specific file patches applied during google3 sync with generic comment-based mechanisms.
By adding `// g3-only` prefix comments to g3-specific exports and declarations, and appending `// 3p-only` context to `@internal` tags, we enable generic tooling to handle these modifications during the sync process.
Additionally, wrap 3rd-party-only imports and exports (which should be stripped in google3) with `// 3p-only-start` and `// 3p-only-end` comment markers.
This reduces the need for maintaining custom file-specific patches in google3.
Also, add a comprehensive guide to these sync comment markers in `contributing-docs/google-markers.md` to assist external contributors.
Specifically:
- Add `// 3p-only` context to `@internal` in `directives.ts` for `foreignImports` and `deferredImports`.
- Add `// g3-only` commented exports in `core.ts`.
- Add `// g3-only-start`/`// g3-only-end` commented global declaration block in `zone.ts`.
- Wrap 3p-only imports in `fake_navigation.ts` with `// 3p-only-start` and `// 3p-only-end`.
- Wrap 3p-only exports in `compiler-cli/index.ts` with `// 3p-only-start` and `// 3p-only-end`.
- Add `// g3-only` and `// 3p-only` markers to `shared.ts` for `setDisabledStateDefault` configuration.
- Add `// g3-only` and `// 3p-only` markers to `feature_detection.ts` for semver dependency.
- Add `// g3-only` and `// 3p-only` markers to `domino_adapter.ts` for domino import path.
- Add `// 3p-only` marker to `ng_dev_mode` import in `event_dispatcher.ts`.
- Add `// g3-only` and `// 3p-only` markers to `MOUSE_SPECIAL_SUPPORT` in `event_contract_defines.ts`.
- Add `// g3-only` and `// 3p-only` markers to `BrowserModule` imports in `module.ts` (animations) and `browser.ts` (testing).
- Add `// 3p-only` marker to `goog.d.ts` reference tags in `util.ts` (platform-browser), `types.d.ts`, `ng_i18n_closure_mode.ts`, `tokens.ts`, and `global_utils.ts`.
- Wrap `Default` enum value of `ChangeDetectionStrategy` in `constants.ts` with `// 3p-only-start` and `// 3p-only-end`.
- Add `// g3-only` and `// 3p-only` markers to `LEGACY_OPTIONAL_CHAINING_DEFAULT` in `legacy_optional_chaining_default.ts` and `legacyOptionalChaining` in `directive.ts`.
- Add `// g3-only` and `// 3p-only` markers to `DEFAULT_PARAMS_INHERITANCE_STRATEGY` in `router_state.ts`.
- Add `// g3-only` and `// 3p-only` (and block variants) markers to `@mcp-b/webmcp-types` imports in `declare_tool.ts`, `provide_tools.ts`, and `types.ts`.
- Add `contributing-docs/google-markers.md` guide.

The default change detection strategy is now OnPush.
BREAKING CHANGE: Component with undefined `changeDetection` property are now `OnPush` by default. Specify `changeDetection: ChangeDetectionStrategy.Eager` to keep the previous behavior.
This change replaces all remaining occurrences of `typeof ngDevMode !== undefined`
with the correct `typeof ngDevMode !== 'undefined'` form. This aligns the codebase
with JavaScript typeof semantics and maintains consistency with other Angular code.
The `requireSynchronousElementRemoval` property was not being passed in all the locations it was needed. This was preventing leave animation timing from behaving properly in some cases.

Since those are top level APIs, `ngDevMode` might not be available at runtime if they're invoked before the variable is set.

This updates tests and examples only to prepare for zoneless by default.
These changes were identified and made as part of #63382. Anything that
failed gets `provideZoneChangeDetection` unless the fixes were easily
and quickly determined.
It also adds the zoneless provider to the `initTestEnvironment` calls
for tests in this repo to prevent regressions before #63382 is merged.

This deprecates the animations package in favor of using `animate.enter` and `animate.leave` with intent to remove the full package in v22.2.
DEPRECATED: @angular/animations

These helpers are often imported by various tests throughout the
repository, but the helpers aren't exported/exposed from the public
entry-point; even though they confusingly reside in there.
This commit fixes this, and moves the helpers into
`packages/private/testing`. This is a preparation for the `ts_project`
migration where we don't want to leverage deep imports between packages.

This aligns with how angular/components marks their hidden APIs.
`@nodoc` has been broken since the switch to adev, this change should
properly hide the APIs again.

We don't need this tooling anymore because we are already validating
that there are no circular dependencies via the `ng-dev` tooling that
checks `.ts` files directly.
Also these tests never actually failed to my knowledge.

Uses `ngServerMode` to automatically disable browser animations on the server. This allows us to decouple `platform-server` from the animations package.
PR Close#59762
Fixes that the async animations renderer didn't have the logic to clean up its style cache during HMR. This is identical to #59393.
Fixes#59640.
PR Close#59644
In https://github.com/angular/components/pull/30179 the CDK overlay started depending on the `Renderer2Factory`. Since the overlay is used in the `MatSnackbar` which is commonly used in error handlers, `Overlay` can end up being injected as a part of the app initialization. Because `AsyncAnimationRendererFactory` depends on the `ChangeDetectionScheduler`, it may cause a circular dependency.
These changes inject the `ChangeDetectionScheduler` lazily to avoid the error.
Note: this will also be resolved by #58984, but I decided to send it out, because:
1. #58984 seems to be stuck on some internal cleanup.
2. The `AsyncAnimationRendererFactory` doesn't need the `scheduler` eagerly anyway so the change is fairly safe.
Fixes#59255.

In some cases apps need to schedule a bit later the loading of the animation module. This private token will allow to investigate which other strategy could be useful.
PR Close#57493
These changes replace most usages of `removeChild` with `remove`. The latter has the advantage of not having to look up the `parentNode` and ensure that the child being removed actually belongs to the specific parent.
The refactor should be fairly safe since all the browsers we cover support `remove`. [Something similar was done in Components](https://github.com/angular/components/pull/23592) some time ago and there haven't been any bug reports as a result.

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 ensures we flush animations by calling renderFactory
begin/end in cases where the ApplicationRef._tick happens in a mode that
skips straight to the render hooks.
PR Close#55564
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.
Also includes the fix for #54919 that got reverted only because it was
easier to revert the set of conflicting commits

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.
