Added a fusion concept inspired by OpenRouter model fusion

Also added an Ultrathink mode.
Anthropic's self-inflicted sanctions triggered the US authorities to act based on the Wassenaar accords. Their Fable model was declared a national security threat (probably based on interesting procedures). This gives even more market to open-weight models and empowers international companies to use alternative models, including Chinese open-weight models. Good news:
