One-shot, idempotent helper that prepares an existing (Chef) node for
Cinc Workstation management: installs Cinc Client, points /etc/cinc at
the existing /etc/chef config, drops the deprecated attribute lists, and
pre-seeds the allowed_* attribute lists so the first converge does not
filter node attributes (e.g. vm_host). The node can then be converged as
usual. Verified against drone-1.
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`
