/**
 * Live smoke for the Capability clean-room chat.
 *
 * Starts the real package server on loopback, opens a clean room, and drives a
 * real runnerd + Codex app-server session through the same HTTP routes the
 * browser uses. It checks that the room starts blank, that a free-form message
 * produces a real Codex turn with semantic tool calls against the mock control
 * plane, that `New chat` rotates the mock identities and retires the previous
 * session, and that nothing in the projected view carries a credential.
 *
 * Requires an authenticated local Codex installation and a built runnerd.
 *
 * Usage: node scripts/capability-clean-room-smoke.mjs [--json]
