The secondary entry point (`node`) within the `@angular-devkit/core` package is
now defined by an exports entry in the main package.json file for the package. This
removes the need for the additional nested package.json file in a subdirectory.
The exports field also contains backward compatible entries to allow for continued
deep imports into the package. These compatibility entries will, however, be removed
in a future major version. Deep imported files are not considered part of the public
API of the package.
This reduces the number of imports for the Node.js file host classes. The `fs` default
import was only used in one place and named imports were already in use for `node:fs`
which allowed the one use to be converted to a named import. The type only import for
`chokidar` was also only used in one type annotation and was moved to the type
annotation directly.
BREAKING CHANGE:
The below APIs have been removed without replacement. Users should leverage other Node.js or other APIs.
- `fs` namespace
- `clean`
- `mapObject`
The dev-infra tooling now directly provides public API change testing capabilities that leverage the `api-extractor` utility. These new testing capabilities are shared with framework and components.
`ts-api-guardian` has been removed as a dependency as a result.
