Freedom from NPM. Happy 4th

Our customers mainly use Donobu's SDK to run their end-to-end tests in CI/CD, with AI self-healing and triage. It was unlicensed but on public npm on purpose, so `npm i` just worked.

NPM registry has had a rough year. When we looked at alternatives, we realized self-hosting packages is not that hard anymore. Our customers continue using `npm i`. They just add a .npmrc pointing at our registry; reusing their existing Donobu API key for auth was a nice bonus.

.npmrc was the only thing needed:

  @donobu:registry=https://api.donobu.com/npm/
  //api.donobu.com/npm/:_authToken=${DONOBU_API_KEY}
