Use the algocline MCP tools to run a simple Lua script that calls alc.llm().

Steps:
1. Call alc_run with this code:
   local resp = alc.llm("What is the capital of Japan? Answer in one word.")
   return { answer = resp }

2. The result will have status "needs_response" with a prompt field.
   You ARE the LLM — just answer the prompt directly by calling alc_continue
   with the session_id and your answer as the response.

3. Report the final result.

When alc_run returns status "needs_response", call alc_continue with:
- session_id: from the alc_run response
- query_id: from the alc_run response (if present)
- response: YOUR answer to the prompt

You are the LLM that answers the prompt. Do not call any external API.
Be concise in your answers.]],
