OpenRouter is a passthrough for providers it does not control, and some transient
provider failures (502/503/529/...) arrive as HTTP 400 with the real status in the
JSON error.code. Retry only those; ordinary 400 invalid-request responses (including
inner error.code == 400) stay non-retryable. Reuses the existing TemporaryError/backoff.
Note: this edits generated code because retry classification here is HTTP-status only
(x-speakeasy-retries) and SDK hooks run outside the retry loop, so a 400 body cannot be
inspected via an overlay or hook. Preserving it across regen needs a genignore or upstream
Speakeasy support -- flagging for maintainers.
