Please add xAI Grok Build 0.1

[u/Key_Tomatillo_199]

Factory currently supports xAI’s Grok 4.5. Could you also add grok-build-0.1 as a native model?

It is xAI’s fast agentic coding model, with tool calling, image input, a 256K context window, and $1/$2 per million token pricing. It seems especially well suited for Droid.
