Can't run just test after checking out airlock

[Providence-o]

After cloning the airlock repo, running just test returns majority failure. When just assets is ran, there are errors indicating that npm is not installed.

I found a solution by:

1. Using this command to install fpm: curl -fsSL https://fnm.vercel.app/install | bash
2. Confirming the installation/version using fnm list
3. Installing the most recent version: fnm install 23.5.0

This then allowed the assets to be built.

It would be good to figure out how to get just test to fail immediately if the assets haven't been built.
