/**
 * OpenAI Responses adapter. Codex speaks the Responses API exclusively
 * (`wire_api="responses"`; Chat Completions support was removed), so to back it
 * with a local model we translate `/v1/responses` to and from the gateway's
 * OpenAI Chat Completions core.
 *
 * Layers:
 * - `responses-wire.ts` — request types
 * - `responses-codec.ts` — JSON request/response translation
 * - `responses-stream.ts` — SSE translation
 * - `openai-responses-wire.ts` — encrypted-reasoning envelopes
 * - `responses-usage.ts` — usage mapping
 * - this module — HTTP handlers that wire the codec to a `Backend`
