/**
 * `omniroute connect <host>` — remote mode.
 *
 * Logs into a remote OmniRoute server and saves the result as the active context
 * so every subsequent command targets that server. Two flows:
 *   - password: prompts for the management password → POST /api/cli/connect →
 *     server mints a scoped access token (default scope: admin).
 *   - token:    `--key <oma_...>` validates via GET /api/cli/whoami and saves it.
