* refactor: move more commands to internal/cmd Part of https://github.com/ooni/probe/issues/1335. We would like all commands to be at the same level of engine rather than inside engine (now that we can do it). * fix: update .gitignore * refactor: also move jafar outside engine * We should be good now?
