Add claude-opus-4-7 model definitions and references to:
- Anthropic direct API types and handler (1M context, prompt caching, extended thinking)
- OpenRouter model sets and fetcher maxTokens override
- Vercel AI Gateway prompt caching and vision+tools sets
- WebView 1M context beta tier pricing check
