Adds 'vercel' as a recognized provider throughout the model resolution system, enabling users with Vercel AI Gateway to use it as a universal fallback for OpenAI, Anthropic, and Google models. The gateway transform infers the sub-provider from canonical model names (claude->anthropic, gpt->openai, gemini->google) and delegates to the appropriate provider-specific transform, producing model strings like vercel/anthropic/claude-opus-4.6.
