- Add OpenRouterWrapper class with OpenAI-compatible API - Support multiple API key environment variables (OPENROUTER_API_KEY, APIKEY_OPENROUTER, OPENROUTER_KEY) - Add OpenRouter model loading in ModelLoader - Add integration test for OpenRouter API access - Handle reasoning models (like pony-alpha) that return content in reasoning field - Support optional HTTP-Referer and X-Title headers for OpenRouter
- Add proper handling for reasoning models (pony-alpha) - Check finish_reason and warn when max_tokens is too small - Use reasoning as fallback only when content is missing - Update test to use larger max_tokens for reasoning models - Simplify test to only test pony-alpha model
