Develop a CLI for beRi that groups renv, rut, and rinse functionality. Make sure that renv, rut, and rinse CLI remain independent of each other and the beRi CLI during this development period.

beRi will vendor the VE, projects, repos, etc inside of a custom location (~/.local/beRi or ~/.beRi). Because of this a standard file-system will need to be conceptualized.

beRi CLI configuration will be done with a YAML file (~/.beRi/<file_name>.yaml).
