- add LIBRARIAN_TIMEOUT config (default 180s) and enforce it with
asyncio.wait_for inside delegate_to_librarian, covering the live
paths (steward direct delegation and SSE streaming) that had no cap
- timeouts fail honestly: success=False with a curated butler sentence,
detail in logs
- set an explicit timeout on TatlockOllamaProvider's AsyncOpenAI client
from OLLAMA_TIMEOUT instead of the SDK default (~600s per LLM call)
- remove the contradictory unused 60s default from
AgentRequest.timeout_seconds; coordination falls back to the
configured budget
