Addressed Copilot review comments in commit 9424748.

• Updated Ollama default chat model references to llama3.1:8b (setup, zero-config, troubleshooting)
• Corrected model-configuration wording (provider flag chooses provider, not model)
• Clarified overwrite prompt behavior (only when output matches templates returned by current search results)
• Clarified OpenAI provider selection is currently via CLI flag --provider openai
• Aligned config YAML example with actual schema (chat_model, timeout as duration strings, scoring *_weight keys)
• Removed unsupported env var override claims (OLLAMA_HOST, OIC_AI_PROVIDER)
• Updated metadata example to schema-valid fields (use_cases, keywords; removed unsupported fields)

Please re-review when convenient.

Overall this looks pretty good to me. I think there is a discussion we should have around further improve this for UX and efficacy but for the intents and purposes of this initial submission this looks good!

Looks Great. We may have a second look once it builds.
