Currently we support safe property (`a?.b`) and method (`a?.b()`) accesses, but we don't handle safe keyed reads (`a?.[0]`) which is inconsistent. These changes expand the compiler in order to support safe key read expressions as well.

As previously discussed in pull/31070 and issues/30486, this would be useful because it is often desirable to apply styles to fields that are both `ng-invalid` and `ng-pristine` after the first attempt at form submission, but Angular does not provide any simple way to do this (although evidently Angularjs did). This will now be possible with a descendant selector such as `.ng-submitted .ng-invalid`.
In this implementation, the directive that sets control status classes on forms and formGroups has its set of statuses widened to include `ng-submitted`. Then, in the event that `is('submitted')` is invoked, the `submitted` property of the control container is returned iff it exists. This is preferred over checking whether the container is a `Form` or `FormGroup` directly to avoid reflecting on those classes.
Closes#30486.

In the dev-infra merge tool, a test fails locally if it runs on
a system with a different system locale. We can either make the
test more flexible, or update the merge tool to always print the date
in `en-US` format. The latter is more reasonable given our console
messages being in english anyway.

With the removal of the `ModuleWithProviders` transform in the parent commit,
the underlying dts transform can also be removed as it is not used elsewhere.
PR Close#41996
The `ModuleWithProviders` type has required a generic type since Angular 10,
so it is no longer necessary for the compiler to transform usages of the
`ModuleWithProviders` type without the generic type, as that should have
been reported as a compile error. This commit removes the detection logic
from ngtsc.

Prior to this change the `min` and `max` validator directives would not
set the `min` and `max` attributes on the host element. The problem was
caused by the truthy check in host binding expression that was
calculated as `false` when `0` is used as a value. This commit updates
the logic to leverage nullish coalescing operator in these host binding
expressions, so `0` is treated as a valid value, thus the `min` and
`max` attributes are set correctly.

When a `trackBy` function is used that accepts a supertype of the iterated
array's type, the loop variable would undesirably be inferred as the supertype
instead of the array's item type. This commit adds an inferred type parameter
to `TrackByFunction` to allow an extra degree of freedom, enabling the
loop value to be inferred as the most narrow type.

Type-only imports are known to be elided by TypeScript, so the compiler
can be certain that such imports do not contribute to potential import
cycles. As such, type-only imports are no longer considered during cycle
analysis.
Regular import statements that would eventually be fully elided by
TypeScript during emit if none of the imported symbols are used in a
value position continue to be included in the cycle analysis, as the
cycle analyzer is unaware of these elision opportunities. Only explicit
`import type` statements are excluded.

Adds the JSDoc `@throws` annotation to functions that would throw
within in the ng-dev tool. We want to add `@throws` so clearly
communicate if the invocation of a function results in errors or not.
This helps if IDEs show the `@throws` annotation on invocation, or
if TS ever lands a feature like Java `throws`, with more fine-grained

If a commit message currently mentions the breaking change or
deprecation note keywords, the commit message parse logic
accidentally picks up the note. This could then accidentally
prevent the commit from being merged (e.g. if the commit targets
the patch branch but mentioned the `BREAKING CHANGE: ` marker).
This commit switches the commit message notes pattern to only
capture notes at the beginning of a line (also allowing accidental
whitespace). This matches with the format we describe in our
contribution guide, as well as with our commit message validation
logic that also assumes notes at the beginning of a line.
PR Close#42436
Currently the commit message validation tool from `ng-dev` validates
the `BREAKING CHANGE:` commit message notes. This commit adds a similar
check for `DEPRECATED:` commit message notes.
Additionally, the check for breaking changes is reworked slightly to
be more tolerant (i.e. if there is only a single line break after the
summary; this is acceptable as per the parser and commonly done in the
COMP repo). The checks have been updated to capture wrong keywords that
are commonly used instead of the correct one. e.g. if a commit message
uses `DEPRECATIONS:` instead of `DEPRECATED:`, the validation will fail.
This prevents changelog generation issues where breaking change notes,
or deprecations are missing. This happened in the COMP repo where
the `DEPRECATED:` keyword was used incorrectly. See:

Updates the outdated build-worker.js file. This file has
been accidentally not updated when we fixed the Octokit
authentication to unblock the caretaker.
We recently updated `@octokit/rest` to a more recent version. For this
the Github client had to be refactored to account for new types of
Octokit. With the refactorings the authentication of the Github
client broke as we used an incorrect option for setting the OAuth
token. The TS transpilation did not fail because the Octokit types
support arbitrary options in the constructor. This is not solvable
on our side, so we cannot prevent similar issues in the future
unfortunately. Adding tests for authentication is not a reasonable
option either.
In the "Interceptor order" section of the HTTP guide there is a typo which incorrectly lists the same service twice when referring to two different services. The order that these services are listed is important, and this commit fixes the typo by listing the services in the correct order.

The compiler flag `compileNonExportedClasses` allows the Angular compiler to
process classes which are not exported at the top level of a source file.
This is often used to allow for AOT compilation of test classes inside
`it()` test blocks, for example.
Previously, the compiler would identify exported classes by looking for an
`export` modifier on the class declaration itself. This works for the
trivial case, but fails for indirectly exported classes:
```typescript
// Component is declared unexported.
@Component({...})
class FooCmp {...}
// Indirect export of FooCmp
export {FooCmp};
```
This is not an immediate problem for most application builds, since the
default value for `compileNonExportedClasses` is `true` and therefore such
classes get compiled regardless.
However, in the Angular Language Service now, `compileNonExportedClasses` is
forcibly overridden to `false`. That's because the tsconfig used by the IDE
and Language Service is often far broader than the application build's
configuration, and pulls in test files that can contain unexported classes
not designed with AOT compilation in mind.
Therefore, the Language Service has trouble working with such structures.
In this commit, the `ReflectionHost` gains a new API for detecting whether a
class is exported. The implementation of this method now not only considers
the `export` modifier, but also scans the `ts.SourceFile` for indirect
exports like the example above. This ensures the above case will be
processed directly in the Language Service.
This new operation is cached using an expando symbol on the `ts.SourceFile`,
ensuring good performance even when scanning large source files with lots of
exports (e.g. a FESM file under `ngcc`).
Fixes#42184.
