When the `ts.Project` creates the language service plugin (in this case,
the Angular Language Service), it sets the project's language service to
the new language service returned by the plugin create:
https://sourcegraph.com/github.com/microsoft/TypeScript@b12af0fa2bbd4b015e59adcfb49988cea7f919a1/-/blob/src/server/project.ts?L2035-2044
The project may be reloaded in response to various events, such as a
change to the tsconfig file, which then recreates the plugin. When this
happens, the language service that gets passed to the plugin `create`
function will not be the typescript language service, but rather the
previous instance of the new language service returned by the last call
to `create`.
This commit ensures that subsequent calls to `create` for the
`NgLanguageService` plugin for a project after the first call are able
to retrieve and hold on to the _TypeScript_ language service.

#51885 patched a call site that threw an error but there were 2 others call that needed to be wrapped in the same way by a try/catch.
`initializeFully` is part of the calls in `responseWith(handleFetch)`.
Same #51885, throwing `SwCriticalError`allows the driver to fallback to `safeFetch` and ensure `responseWith` doesn't fail.

When adding a new view flag, you currently need to adjust the last number of the last
3 flags. All of these share the same number so the shifting ones can just use
the base-10 IndexWithinInitPhaseShift.

This PR moves the Observable subscription of toSignal outside of the
reactive context. As the result the toSignal calls are allowed in the
computed, effect and all other reactive consumers.
This is based on the reasoning that we already allow signals creation
in a reactive context. Plus a similar change was done to the async pipe
in the https://github.com/angular/angular/pull/50522Fixes#51027

This commit updates hydration runtime code to avoid creating an empty array when we can avoid it. Instead, we just check whether the field is `null` directly (without using nullish coalescing).

We control most flags via Starlark and therefore limit configuration
options via `tsconfig` to a minimum. We do not intend to support the
enabled block types option via Starlark, so this commit allows for
the option to be picked up.
(This is useful for benchmarking the new control flow blocks).

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.

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.

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.

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.

This flag allows message event listeners to prevent callbacks from executing within the NgZone if they contain a special `__ignore_ng_zone__` flag.
This functionality is built with Angular DevTools in mind, where it prevents an infinite change detection loop in inspecting applications that have message event listeners:
CD -> Inspected app emits componentTreeDirty event to DevTools -> DevTools emits event to get new component Tree from Inspected app -> Inspected app message event listener fires -> CD

This commit switches the signals library from a bidirectional symmetric
dependency graph using weak references, to a bidirectional _asymmetric_
graph which uses strong references. This is made possible with a reference
counting algorithm which only tracks producer -> consumer references for
effect-like "live" consumers, preventing memory leaks.
The new algorithm should be simpler and faster than the previous
implementation as weak references are fairly slow to create and traverse.
A tradeoff is that non-live consumers must now poll their producers when
read, as they cannot rely on dirty notifications.
As part of this refactoring, the `ReactiveNode` class is replaced with an
interface instead, and methods are moved to standalone functions. This is
paired with instantiating individual signals/computeds via `Object.create`
against a prototype node which contains static or initial values. This
technique, in conjunction with the rest, greatly improves the performance
of node creation.

Rather than the navigation transitions managing Router state, this
commit updates the Router to manage its own state based on ongoing
transition events. In the future, this can be abstracted even further to
have a totally separate class that manages the Router state. This would
allow the potential for swapping state manager implementations rather
than having to implement all types of state management in a single place.
One finding during tests was that unexpected errors thrown by the state management code moved
to the Router here will no longer be caught by the transition pipe's `catchError`.
This only includes calls to the following public Api methods:
* `go`, `replaceState`, `historyGo`, `isCurrentPathEqualTo` on `Location`
* `UrlSerializer.serialize`
* `UrlHandlingStrategy.merge`.
None of these methods should throw if the router is expected to function.
These might throw when tests include incomplete mocks, which is not
supported, or in cases where the actual browser methods like
`replaceState` would throw. This will already result in unexpected/unsupported
behavior. The failure case here is now arguably better - the navigation
itself still completes but the state update (either updating Router
internal state or updating the browser URL) fails separately and is
unhandled.

Angular 16.1 introduced the input transform feature, requiring the partial compilation output to be extended
with a reference to the input transform function. This has resulted in a subtle breaking change, where older
versions of the Angular linker can no longer consume libraries that have started to use this feature.
We do try to support using a 16.1 library from an Angular 16.0 application, but if a library actually
adopts a new feature then this is no longer possible. In such cases, it is desirable to report a message
telling the user that their version of the Angular compiler is too old, as determined by the `"minVersion"`
property that is present in each partial declaration. This version would still indicate that the declaration
required at least Angular 14.0 to be compiled, but this is not accurate once input transforms are being
used. Consequently, this error would not be reported, causing a less informative error once the input transform
was being observed.
