Just discovered the sbt start script plugin: https://github.com/typesafehub/xsbt-start-script-plugin:

This plugin allows you to generate a script target/start for a project. The script will run the project "in-place" (without having to build a package first).

The target/start script is similar to sbt run but it doesn't rely on SBT. sbt run is not recommended for production use because it keeps SBT itself in-memory. target/start is intended to run an app in production.

The plugin adds a task start-script which generates target/start. It also adds a stage task, aliased to the start-script task.
