Mirror the existing /v1/messages platform split pattern: - OpenAI groups → OpenAIGateway handlers (existing, unchanged) - Non-OpenAI groups → Gateway handlers (new Anthropic-upstream path) Updated both /v1 prefixed routes and non-prefixed alias routes (/responses, /chat/completions). WebSocket route (/v1/responses GET) remains OpenAI-only as Anthropic has no WebSocket equivalent.
