Cinc Workstation replaces Chef Workstation for driving knife-zero and Test Kitchen; nodes run (or are moving to) Cinc Client. - Pin .ruby-version to cinc-workstation - Move knife config from .chef/ to .cinc/ (Cinc's USER_CONF_DIR) and update .gitignore, README, AGENTS and docs accordingly. On-node config now lives in /etc/cinc - Drop the Gemfile/Gemfile.lock; install knife-zero into Cinc Workstation's user gem dir with `cinc gem install knife-zero` - README: rewrite setup/usage for Cinc Workstation - scripts/postgresql/switch_primary.sh: drop `bundle exec`
