Registers Cheaper Inference (api.cheaperinference.com) as an OSS-sponsor gateway provider.

- Canonical provider `cheaperinference` (alias `cinf`) + routing registry with 39 measured text models
- Dedicated executor: forces `store:false` on the native /v1/responses endpoint (the shared strip in
  chatCore.ts deletes `store` for every provider != openai, so without this every Responses request
  400'd) and resolves chat-vs-responses URL from the per-model targetFormat
- 3 image models (grok-imagine, nano-banana-pro, nano-banana-2), prefix-only: the two nano-banana ids
  already belong to adobe-firefly, which keeps the bare-id routing
- Resale pricing measured from GET /v1/models (30% off list); sponsor rail Kimi 1st / Cheaper
  Inference 2nd via an explicit rank map; supporter badge in 43 locales; README row

No quota card: the gateway exposes no balance API (/v1/wallet and /v1/balance both 404).

Validated live end-to-end through OmniRoute: chat, native Responses, streaming and image generation
all 200 with real content; the Firefly collision guard verified at runtime.

+ *
+ * The endpoint ignores `response_format:"url"` and always returns `b64_json`

+ *
+ *  1. `/v1/responses` is STATELESS and REQUIRES `store:false`. Omitting it returns
+ *     HTTP 400 ("This Responses-compatible endpoint is stateless. Send store=false…").
+ *     chatCore.ts deletes `store` for every provider except "openai" — a strip shared
+ *     by ~290 providers that must not be special-cased — so we re-add it here, after
+ *     that strip has run. A client-supplied `store:true` is overwritten rather than
+ *     forwarded: the endpoint cannot honour it, and forwarding would 400.
+ *
+ *  2. Chat and Responses live at DIFFERENT URLs (unlike providers that switch on a
+ *     path suffix). The per-model `targetFormat` registry tag is the single source of
+ *     truth for which surface a model uses — the same tag chatCore reads to translate
+ *     the body — so resolving the URL from it keeps URL and payload in lockstep.
