/**
* Builds the Oak application and, when run directly, starts the recurring
* jobs and listens on {@link LISTEN_HOST}:{@link PORT}, having first signed
* the users out of other instances if they may no longer sign in there
* (`FEDERATION.outgoing`). A request goes
* through the error middleware, the compression of what is answered, the OG
* tags and CORS, then the routers, one
* per resource of the API (`API.md` lists them), and last the built frontend,
* which answers every path no router did.
