chore(query-keys): restore the visit invalidation bundle with its consumers

The bundle landed a release before the surfaces that read it and was removed
on trunk as dead. Both mutation hooks in this branch use it, and the merge took
trunk's deletion, so it comes back here together with the writes that need it.
The comment now names its consumers, so the next dead-code sweep can see them
without reading two files.
