 All CI actions implicitly require this function to be executed. Its purpose is to provide a consistent execution environment for project-level activities. For example, by using a consistent `BUILD_PACKAGED_DIST` variable, CI actions creating an output zip file, NPM package, or APK can all place their artifacts in consistent locations.
