This commit updates the TypeScript configuration across the project to use `moduleResolution: "bundler"`. This modernizes our module resolution strategy to align with current TypeScript best practices and bundler behaviors.
The following changes are included:
- Updated `tsconfig.json` files to set `moduleResolution` to `"bundler"`.
- Updated the `rules_angular` bazel dependency to a version compatible with these changes.
- Adjusted related test files and golden files to reflect the new module resolution strategy.

This works for the code actions and completion. When the ls wants to complete
all importable angular metadata in the template, the ls will invoke the function
`ls.getCompletionsAtPosition` and filter the item about the angular. When the
developer selects an item, the ls will get the module specifier from the code action
return by the `ls.getCompletionEntryDetails`.

Currently the `makeProgram` utility from `ngtsc/testing` does not use
the test host by default- optimizing for source file caching.
Additionally, the host can be updated to attempt caching of the `.d.ts`
files from `@angular/core`— whether that's fake core, or the real core-
is irrelevant. We are never caching if these changes between tests, so
correctness is guaranteed.
This commit reduces the type check test times form 80s to just 11
seconds, faster than what it was before with `fake_core`. The ngtsc
tests also run significantly faster. From 40s to 30s

This commit replaces `fake_core` with the real `@angular/core`
output. See previous commit for reasons.
Overall, this commit:
* Replaces references of `fake_core`
* Fixes tests that were testing Angular compiler detection that _would_
already be flagged by type-checking of TS directly. We keep these
tests for now, and add `@ts-ignore` to verify the Angular checks, in
case type checking is disabled in user applications- but it's worth
considering to remove these tests. Follow-up question/non-priority.
* Adds `@ts-ignore` to the tests for `defer` 1P because the property is
marked as `@internal` and now is (correctly) causing failures in the
compiler test environment.
* Fixes a couple of tests with typos, wrong properties etc that
previously weren't detected! A good sign.

Fixes that a query like `viewChild('locator', {read: ElementRef<HTMLElement>})` would throw because we didn't account for expressions with type parameters.
I've also included support for parenthesized expressions and `as` expressions since it's pretty easy to support them.
Fixes#54645.

Currently we have two fake copies of `@angular/core` in the compiler tests which can be out of sync and cause inconsistent tests. These changes reuse a single copy instead.

Fixes that `ɵunwrapWritableSignal` inferring getter functions as not matching the interface of `WritableSignal` instead of preserving them.
PR Close#54252
In a previous commit the TCB was changed to cast the assignment to an input in order to widen its type to allow `WritableSignal`. This ended up breaking existing inputs whose setter has a wider type than its getter. These changes switch to unwrapping the value on the binding side.

Reworks the TCB for two-way bindings to make them simpler and to avoid regressions for two-way bindings to generic inputs. The new TCB looks as follows:
```
var _t1: Dir;
var _t2 = _t1.input;
(_t1 as typeof _t2 | WritableSignal<typeof _t2>) = expression;
```

Adds compliance output tests for `output()` to verify that
we are emitting proper full compilation output, as well as proper
partial compilation output that can be linked to match the full output.

This commit separates `InputSignal` for input signals with transforms.
The reason being that most of the time, signal inputs are not using
transforms and the generics are rather confusing.
Especially for users with inferred types displayed in their IDEs, the
input signal types are seemingly complex, even if no transform is used.
For this reason, we are introducing a new type called
`InputSignalWithTransform`. This type will be used for inputs with
transforms, while non-transform inputs just use `InputSignal`.
A notable fact is that `InputSignal` extends `InputSignalWithTransform`,
with the "identity transform". i.e. there is no transform. This allows
us to share the code for input signals. In practice, we don't expect
users to pass around `InputSignal`'s anyway.

Adds a compiler integration test for recognizing signal-based queries,
and emitting the expected output. Concrete output will be verified via

Currently internally Angular has some customized tsconfig files, because we don't align with the tsconfig of the rest of g3. These changes enable `noImplicitReturns` and `noPropertyAccessFromIndexSignature` to align better with the internal config.

When we create a context to inject inside our ngTemplateOutlet, the context was declare as Object, therefore, there are no compilation error.
Now if we add a context, we get error at compile type.
BREAKING CHANGE: If the 'ngTemplateOutletContext' is different from the context, it will result in a compile-time error.
Before the change, the following template was compiling:
```typescript
interface MyContext {
$implicit: string;
}
@Component({
standalone: true,
imports: [NgTemplateOutlet],
selector: 'person',
template: `
<ng-container
*ngTemplateOutlet="
myTemplateRef;
context: { $implicit: 'test', xxx: 'xxx' }
"></ng-container>
`,
})
export class PersonComponent {
myTemplateRef!: TemplateRef<MyContext>;
}
```
However, it does not compile now because the 'xxx' property does not exist in 'MyContext', resulting in the error: 'Type '{ $implicit: string; xxx: string; }' is not assignable to type 'MyContext'.'
The solution is either:
- add the 'xxx' property to 'MyContext' with the correct type or
- add '$any(...)' inside the template to make the error disappear. However, adding '$any(...)' does not correct the error but only preserves the previous behavior of the code.

This commit implements the next step of Angular's "standalone" functionality,
by allowing directives/components/pipes declared as `standalone` to be imported
into NgModules. Errors are raised when such a type is not standalone but is
included in an NgModule's imports.

As outlined in the previous commit which enabled the `esModuleInterop`
TypeScript compiler option, we need to update all namespace imports
for `typescript` to default imports. This is needed to allow for
TypeScript to be imported at runtime from an ES module.
Similar changes are needed for modules like `semver` where the types incorrectly
suggest named exports that will not exist at runtime when imported from ESM.
This commit refactors all imports to match with the lint rule we have
configured in the previous commit. See the previous commit for more
details on why certain imports have been changed.
A special case are the imports to `@babel/core` and `@babel/types`. For
these a special interop is needed as both default imports, or named
imports break the other module format. e.g default imports would work
well for ESM, but it breaks for CJS. For CJS, the named imports would
only work, but in ESM, only the default export exist. We work around
this for now until the devmode is using ESM as well (which would be
consistent with prodmode and gives us more valuable test results). More
details on the interop can be found in the `babel_core.ts` files (two
interops are needed for both localize/or the compiler-cli).

With the changes to support APF v13 in the `ng_package` rule, we have
removed the ambiguous `entry_point` attribute. The attribute suggested
that it would be used for determining the primary entry-point input
file. This was not the case as the flat module output file is consulted
for bundling et at. The attribute has been renamed to match its
purposed (renamed to `primary_bundle_name`).
We no longer need to set that attribute because the primary bundle
name is (1) not of relevance for consumers and (2) the rule already
infers the bundle name properly from the Bazel package.

In #41995 the type of `TrackByFunction` was changed such that the
declaration of a `trackBy` function did not cause the item type to be
widened to the `trackBy`'s item type, which may be a supertype of the
iterated type. This has introduced situations where the template type
checker is now reporting errors for cases where a `trackBy` function is
no longer assignable to `TrackByFunction`.
This commit fixes the error by also including the item type `T` in
addition to the constrained type parameter `U`, allowing TypeScript to
infer an appropriate `T`.
