Scope finalizers don't run on runtime shutdown

[kciesielski]

Ox offers a nice way to manage resources in scopes:

supervised {
  val serverBinding = useInScope(NettySyncServer().addEndpoints(endpoints).start())(_.stop())
  //...
  never
}

The release clause (_.stop()) is run only if the scope fails due to an unhandled exception. We often deal with long-living resources which should get released on server shutdown, which typically means a TERM signal to the JVM, handled by a shutdown hook. This is handled in Cats Effect by IOApp, where users can compose resources into a final effectIO[ExitCode]. In case of runtime shutdown,main fiber will be canceled and resource finalizers will be called. Maybe we can somehow achieve a similar effect in Ox? There is no notion of App, main fiber etc., but I'm leaving this issue as a remark that using resources in scopes has this particular limitation.
