AgentFn adapter that calls an OpenAI-compatible POST /chat/completions endpoint using @uncaged/workflow’s LlmProvider (base URL, API key, model).

Single-turn: system text is the current role’s systemPrompt, user text is the thread’s initial prompt (ctx.start.content). Errors from HTTP, JSON, or empty choices are thrown as Error with a JSON payload string.
