Updated documentation to: - Mark model parameter as optional with default value openai("gpt-4.1") - Remove unused model variable declaration - Update all code examples to show inline model specification - Replace "Migration" section with "Model Configuration" showing optional usage - Add examples for multiple model providers (OpenAI, Anthropic) - Show that model can be omitted to use default This aligns the documentation with the actual implementation in cloudflare/agents PR #849 where model was made optional.
