//! OpenAI Responses WebSocket protocol entry point, session engine, and adapters.
//!
//! The route is protocol-oriented. `session` bootstraps the authenticated
//! connection, `connection` owns the socket FSM, `client` and `quota` own
//! protocol/retry policy, and `lifecycle`/`turn` bridge each turn into the
//! existing usage and audit runtime. Adapters contain only provider-specific
//! connection and metadata behavior.
