test: Add tests for main package

- Changed jest to run from the root package and reference the packages
  as projects. This required moving the base jest config file away from
  the project root.
- Module isolation seems to prevent ts-jest from loading the shared
  package, so we disabled it for now.
- To better facilitate mocking, services should be split into interfaces
  and implementation
- Had to downgrade to chald 4.1.2 as per
  https://github.com/chalk/chalk/releases/tag/v5.0.0 at least until
  https://github.com/microsoft/TypeScript/issues/46452 is resolved.
