George Kalpakas 935cf433ed fix(docs-infra): support recovering from unrecoverable SW states (#39651)
Occasionally, the SW would end up in a broken state where some of the
eagerly cached resources of an older version were available in the local
cache, but others (such as lazy-loaded bundles) were not. This would
leave the app in a broken state and a blank screen would be displayed.
See #28114 for a more detailed discussion.

This commit takes advantage of the newly introduced (in v11)
[SwUpdate#unrecoverable][1] API to detect these bad states and recover
by doing a full page reload whenever an [UnrecoverableStateEvent][2] is
emitted.

Partially addresses #28114.

NOTE:
Currently, `SwUpdate.unrecoverable` only works if the app has already
bootstrapped; i.e. if only lazy-loaded bundles have been purged from the
cache.
That should be fine in practice, since the cache entries are removed in
least-recently-used order. Thus the eagerly loaded bundles will be the
last to be removed from the cache (which rarely happens in practice).

public-api/

This directory contains all of the public api goldens for our npm packages we publish to NPM. These are tested on all PRs and commits as part of the our bazel tests.

To check or update the public api goldens, run one of the following commands:

yarn public-api:check
yarn public-api:update

packages-circular-deps.json

This golden file contains a list of all circular dependencies in the project. As part of the lint CI job we compare the current circular dependencies against this golden to ensure that we don't add more cycles. If cycles have been fixed, this file is also updated so that we can slowly burn down the number of cycles in the project.

To check or update the golden, run the following commands:

yarn ts-circular-deps:check
yarn ts-circular-deps:approve
