Curviate: job postings and applicants

Every posting starts as a draft. Drafts are free and reversible; publishing is neither. The two things that surprise agents here are that a free publish is still subscription-gated and that an update's read-back lags the write.

Command surface established against CLI 0.33.0.

Before any command

npm install -g @curviate/cli && curviate --version    # needs Node 18 or newer
curviate login --api-key <key>                        # or export CURVIATE_API_KEY
curviate account list --json                          # the acc_id for --account
