feat(api): add OpenRouter API client with structured response handling

- Implemented data models for OpenRouter API response including OpenRouterModel, ModelPricing, and ProviderInfo.
- Created a main function to fetch and parse models from the OpenRouter API.
- Added error handling for JSON parsing and displayed model statistics (free vs paid).
- Enhanced output with raw response length and first few model IDs.
