* chore: remove duplicate code of conduct
* chore: remove AUTHORS file
I doubt this actually has any value in the era of GitHub.
* chore: move CODEOWNERS to toplevel
* chore: move CONTRIBUTING.md to toplevel and adapt it
* chore: remove duplicated LICENSE file
* chore(engine): remove now-obsolete design document
* chore: remove the testusing test
We're not going to make this code importable from third parties
like we did for probe-engine. It seems this feature was only used
for the experiment in Spain so it makes sense to drop it.
* chore: enable code generation tests
See https://github.com/ooni/probe/issues/1335
* chore: enable code-ql checks
* cleanup: remove libooniffi code and tests
It seems this code is not used. We are not aware of anyone using it. And we
don't want to expose it publicly as an API. So, what to do?
I guess it's fine to delete it. If there is anyone that needs it, we have
in the history a reference to it and we can always reinstate it.
* chore: move issue templates to ooni/probe
