BREAKING CHANGE:
The experimental workspace API has been removed from `@angular-devkit/core`. This API was no longer used by the Angular CLI and was replaced with the stable workspace API also found within `@angular-devkit/core`. This change does not affect project code and is related to tooling infrastructure only.
This API is already experimental. The move allows for the new stable API to use the "workspace" directory structure and to also better signify that the existing API is in fact experimental and subject to change or removal.
* refactor: fix `import` and `export` paths to work with classic resolution
`ts-api-guardian` only support classic module resolution which means that we need to specify `index` so that the resolution works.
* build: add `npm_package` to packages
* build: add ts-api-guardian to repo
* test: add api golden files
* refactor: use proper namespace instead of alias export
* refactor: use proper namspace einstead of alias export
* build: add `_golden_api` files
At the moment ts api guardian doesn't support aliased symbols as namespaces, this is a workaround to still have namespaced symbols in the final golden file.
* build: update angular archive for workspace
* test: fix reference to `TestHost` to use namespace
* refactor: create `fs` namespace instead of aliased export
* test: update api golden file for `@angular-devkit/core/node`
