Configurable LLM request timeout per provider/model (Ollama cold-start causes silent fallback)
증상
When using local Ollama models, the first request after model load triggers a cold-start that takes ~13-46 seconds (depending on model size). The default LLM request timeout in OpenClaw appears too short for this scenario, causing a timeout-based fallback (status 408) to the next model in the fallback chain — typically a cloud model.

OpenClaw gateway, skill, or agent configuration issue — root cause confirmed in the openclaw/openclaw issue tracker.
해결법
Pre-load models before use via the Ollama API:
curl http://192.168.178.122:11434/api/generate \
-d '{"model":"qwen3.5:122b","prompt":"hi","stream":false,"keep_alive":"60m","options":{"num_predict":1}}'
This forces the model into memory with a 60-minute keep-alive, avoiding cold-start timeouts on subsequent requests. However, this requires manual intervention or scripting before each session.
