CLI version 2.4.2

Version 2.4.2 of the CLI fixes the following bugs:

• When the CLI does not detect Yarn, it now provides installation instructions instead of only reporting that Yarn is absent.
• The CLI no longer parses the frontastic binary file as a configuration file when it is present in the execution directory.
• To increase accuracy, the guid validation pattern in the code generator is now stricter.
• Long messages no longer overflow onto the right border of the CLI log view.
• The upload of a backend extension no longer fails on the first invocation of the CLI in a newly cloned repository, which means you no longer need to restart the CLI.
