Summary

The OpenRouter plugin's predefined catalog currently stops at the gpt-5.6-* and claude-*-5 series, while OpenAI's GPT-6 / GPT-6.1 series and Anthropic's Claude 5.5 / Fable 5 series are live on OpenRouter (and already added to the native OpenAI and Anthropic plugins in #3918, #3919, and #3811).

This PR adds the 13 missing predefined models (verified against GET https://openrouter.ai/api/v1/models):
