- call Shutdown to close connections before exit
- exit with status 0 on shutdown
- call Shutdown in the main thread because it blocks while
ListenAndServe exits immediately
- Shutdown waits for requests to complete. We pass the signal context to
the server so it derives the request contexts from that. The
long-running GET request handler already stop on context cancellation.
- unregister signals before shutdown so that a second Ctrl-C will hard-exit
