Run an Arachne application, terminating it as soon as it has successfully started.

This is useful for 'build'-like tasks where you want to perform some processing as defined by an Arachne config, but not start a long-lived appliation. The tasks of building assets or deploying an application often falls into this category, for example.

Arguments:

module - A Clojure keyword identifying an Arachne module or application. Usually this is defined in an `arachne.edn` file on the root of the classpath in the current project.
runtime - A Clojure keyword identifying the runtime that should be started. The runtime must have been defined in the Arachne configuration for the module specified by the module argument.

The application will terminate gracefully when processing is complete.
