* fix: fix repo switching Extend the functionality of repo switching by creating a backup before the switch. Also implement a rollback mechanic in case of an error. Signed-off-by: Dominik Willner <th33xitus@gmail.com> * refactor: fail when installing requirements fails Signed-off-by: Dominik Willner <th33xitus@gmail.com> * refactor: display owner and repo in main menu on separate lines long owner and repo names would case the menu to be too wide Signed-off-by: Dominik Willner <th33xitus@gmail.com> --------- Signed-off-by: Dominik Willner <th33xitus@gmail.com>
