You probably needed to run composer install again. That's a general matter of working with git+composer: after updating the git repo, the composer.json and composer.lock files may have changed. (Specifically, around the time of #70/#73, the composer.json did change -- so that the class Civi\Cv\Bootstrap would be available.) Running composer install should update the dependencies.
