Walkthrough

Adds support for RelayModeResponses in the Cloudflare adaptor: request URL construction for /ai/v1/responses, passthrough converters for OpenAI requests, and response handling with non-stream and stream paths delegating to OpenAI bridge handlers. Existing modes (chat completions, embeddings, audio) remain unchanged.

Changes

Cohort / File(s)	Summary of Changes

Poem

I twitch my ears at new reply modes’ gleam,
Hopping through routes where responses stream.
A gentle nudge to /ai/v1 we go,
Handlers hum softly, data starts to flow.
With every hop, the paths align—
Requests in rhythm, replies divine. 🐇✨
