This change contains runtime logic needed to flatten the NgModule bootstrap field in local compilation mode. While it is quite odd to pass a "nested" array as NgModule bootstrap, it is still required to support this case in local compilation mode since it is supported in full compilation mode.
PR Close#51767
Today in local compilation mode the NgModule bootstrap definition is moved as it is into the runtime `ɵɵdefineNgModule`. This runtime was initially made for AoT full compilation mode and assumes that the bootstrap info is already flattened and resolved. This is not the case in local compilation where the bootstrap is the raw expression coming from the NgModule decorator and can be a nested array. To get around this problem we move the bootstrap along with other scope info (e.g., declarations, imports, exports) to the runtime`ɵɵsetNgModuleScope` to be further analyzed and flattened in runtime.

This change flattens the imports info on standalone component decorators in runtime dev mode by adding flattening logic to the deps tracker. Such flattening has no effect in AoT full compilation mode since these arrays are already resolved and flattened by AoT static analysis, but in local compilation mode it is needed since the raw array as appears on the component decorator will be passed to the deps tracker, and so it needs to be flattened.
This change does not affect prod runtime since deps tracker is only used in dev mode.

This change flattens the imports/exports/declarations info on ngModule decorators in runtime dev mode by adding flattening logic to the runtime `ɵɵsetNgModuleScope`. Such flattening has no effect in AoT full compilation mode since these arrays are already resolved and flattened by AoT static analysis, but in local compilation mode it is needed since the raw array as appears on the NgModule decorator will be passed to the runtime `ɵɵsetNgModuleScope`, and so it needs to be flattened.
This change has to effect on prod runtime as `ɵɵsetNgModuleScope` is not used in prod.

Currently when ESBuild bundles an application importing from
`@angular/core`, the signals library will be discovered during
export analysis. ESBuild will come across the constants for the reactive
signal graph- and end up considering some of these as side-effects given
the pattern of using a spread assignment for extending from e.g.
`REACTIVE_NODE` (a similar issue may occur if we e.g. extend from the
computed reactive node).
See more details on the issue: https://github.com/evanw/esbuild/issues/3392
Even though, ESBuild preserves these constants now, and all of its
dependencies— Terser will consider these as side-effect free and
eliminate these constants. This may require multiple passes though, and
might not be sufficient, depending on the chain of reactive node
extensions. E.g. in the signals branch we noticed some constants
unnecessarily being preserved.

This expands on the extraction with information for directives, including inputs and outputs. As part of this change, I've refactored the extraction code related to class and to directives into their own extractor classes to more cleanly separate extraction logic based on type of statement.

This commit adds a barebones skeleton for extracting information to be used for extracting info that can be used for API reference generation. Subsequent PRs will expand on this with increasingly real extraction. I started with @alxhub's #51615 and very slightly polished to get to this minimal commit.

This commit adds support for zone.js 0.14.0 and drops support for older versions
BREAKING CHANGE: Angular now required `zone.js` version `~0.14.0`
PR Close#51774
Another try at deflaking the tests on Windows. I'm trying a couple of fixes here:
1. I noticed that it's usually the indexer tests that fail during flaky runs. These tests also happen to be the only ones that don't pass in the `files` argument of `NgtscTestEnvironment.setup`. When `files` isn't passed in, we don't hit the file path that sets up the `MockFileSystem`. With these changes I make it so that we always initialize the mock file system.
2. The missing file system error usually comes from the `absoluteFrom` call that initializes the optional `workingDir` argument. My theory is that because it's a default value for an argument, it gets called too early before everything is initialized. These changes move the `absoluteFrom` call further down until it's needed.

upgrade the warning for lazy-loaded lcp images when using NgOptimizedImage to an error
BREAKING CHANGE:
Previously when NgOptimizedImage directive detected that an LCP image is lazy-loaded, a console warning was produced. Now the directive throws an error to make it more discoverable in a console. If you receive this error, refer to this guide for additional information: https://angular.io/guide/image-directive#step-4-mark-images-as-priority

Terser does not treat `Symbol` as side-effect free- so if we end up with
a symbol export being loaded, it will result in the symbol being
retained.
We noticed this in the signals prototyping where symbols exported
from `computed` ended up appearing in symbol bundling tests.

Certain code patterns and tools in Google (and possibly 3P world) lead to the situation that a component is bootstrapped/rendered without its ng-module being loaded in the browser. Technically speaking this should be an anti-pattern since the ng-module could contain some runtime logic (e.g., providing something, calling some services, etc) and its not being loaded leads to unexpected behaviour. However, in many cases ng-module is an empty class and its only usage is for providing scope, and since in AoT full compilation mode we already hard-code dependencies into components so we can get away with not loading the ng-module. But in AoT local compilation mode it is not possible to get away since the component's dependencies are computed in runtime and the presence of the corresponding ng-module in the browser is needed. For this reason in this change it is forbidden to attempt to render a component without first loading its ng-module in local compilation mode and an explicit error message is created to make this situation clear. This error message can help with catching such cases when running TGP in Google.
It would be an interesting question as to whether to ban this situation in full compilation mode as well, as it is error prone and these errors are sometimes very hard to debug.

This commit removes access to deep imports and `zone-testing-bundle` and `zone-testing-node-bundle`
This commit removed access to deep and legacy `dist` imports. `zone-testing-bundle` and `zone-testing-node-bundle` are also no longer generated.
BREAKING CHANGE:
Deep and legacy `dist/` imports like `zone.js/bundles/zone-testing.js` and `zone.js/dist/zone` are no longer allowed. `zone-testing-bundle` and `zone-testing-node-bundle` are also no longer part of the package.
The proper way to import `zone.js` and `zone.js/testing` is:
```js
import 'zone.js';
import 'zone.js/testing';
```

This commit adds explicit type annotations to the reactive node prototype objects,
such that the prototypes are type-checked against the interface they are supposed
to (partially) implement. This also allows IDEs to better track usages of reactive
node properties, improving code navigation.

When a producer is no longer used, the consumer has to update its internal data structure
that keeps track of all producers. There used to be an issue where only half of the stale
producers would actually be removed from this data structure, as the intended upper bound
of the number of producers to remove would decrease with each removed producer, therefore
not reaching all producers that should be removed from the data structure.
This commit fixes the issue by truncating the arrays directly, without going through
individual `pop` operations. An assertion that would catch the inconsistent state in
the internal data structures of the signal graph has been introduced.

The `verifyPlaceholdersIntegrity` check in the compliance tests was basically a noop, because it was returning false inside a `forEach` callback. Fixing it revealed that it had fallen out of date, because one of the regexes it uses was incorrect. The problem is that it assumed the placeholder keys would always be string literals, however it's possible that they're identifiers. These changes resolve the issue by not looking at the keys at all since we don't do anything with them.
