// Arcadia LLM-gateway client.
//
// The integration registry lives on arcadia-llm-gateway, not arcadia-app, so
// it needs its own ArcadiaClient pointed at a different base URL. Everything
// else is identical to the arcadia-app client: the same access token (the
// gateway validates arcadia-app JWTs via the shared Guardian secret) and the
// same 401 cleanup. The gateway's CORS already allows localhost + any
// *.sky-ai.com origin, so the browser calls it directly.
