/**
 * Smoke tests for the new `agentctl kandev …` subcommand groups.
 *
 * Each test spawns the `agentctl` binary directly with the same env
 * vars the office runtime injects at agent launch (KANDEV_API_URL,
 * KANDEV_API_KEY, KANDEV_WORKSPACE_ID, …) and asserts the request
 * round-trips through the backend's office API. The `KANDEV_API_KEY`
 * is a real runtime JWT minted via the existing
 * `/api/v1/_test/runtime-token` helper, so the agent auth middleware
 * sees a valid token instead of falling through to admin mode.
 *
 * Why these tests: the agentctl CLI is now the canonical surface for
 * every office mutation the CEO makes. Without coverage, an endpoint
 * rename / payload-shape drift on the backend would silently break
 * the CEO's CLI without any unit test catching it.
