/**
 * Step: cli-agent — Create the scratch CLI agent for `/new-setup`.
 *
 * Thin wrapper around `scripts/init-cli-agent.ts`. Emits a status block so
 * /new-setup SKILL.md can parse the result without having to read the
 * script's plain stdout.
 *
 * Args:
 *   --display-name <name>   (required) operator's display name
 *   --agent-name   <name>   (optional) agent persona name, defaults to display-name
 *   --folder       <name>   (optional) explicit folder name, defaults to cli-with-<normalized-display-name>
