Summary
Routes gpt-5.6-luna through the Responses API required by the Opencode Go gateway.
Fixes #1431: [BUG] OpenCode Go returns HTTP 500 for GPT-5.6 Luna via /chat/completions; model works via /responses #1431
Description
Opencode Go recently started producing 500 errors when using gpt-5.6-luna model. These errors are only happening on the /v1/chat/completions endpoint (OpenAI legacy API). GPT 5.6 Luna uses the newer Responses API on the /v1/responses endpoint, and requests to this endpoint are working.
The Zoo Code Opencode Go provider currently does not implement the responses api, however Zoo Code core provides transforms to support the responses API and there are examples of this implemented in other providers.
This fix provides an implementation of the responses api for the Opencode Go provider, so that specified models may utilise the Go /v1/responses api endpoint instead of /v1/chat/completions. This resolves the 500 error.
