LLM and Authentication Variables

The backend relies on these secrets to talk to model providers, orchestrate researcher/report agents, and enable OAuth flows.

LLM_CONFIGS

1. Decide which providers you want to use (OpenAI-compatible, Anthropic, Gemini, etc.).
2. For each provider, collect the API key and base URL if the provider requires a custom endpoint.
3. Build a JSON array describing each model, e.g.:

   [
     {
       "provider": "openai",
       "model": "gpt-4o-mini",
       "apiKey": "sk-your-key",
       "baseUrl": "https://api.openai.com/v1",
       "maxRetries": 3
     }
   ]

4. Paste the serialized JSON blob into LLM_CONFIGS (wrap the value in single quotes inside .stack.env so special characters survive).
