This also runs the tests for contextlink, which I think we previously
never ran. I don't see any other packages that define an `npm test`
command. Having to manually list all the sub-package test directories in
the top-level package.json is a bit unfortunate, but it works.
For Puter itself we support Node 16.x IIRC, but Phoenix requires at
least 20.x currently.
