Streams resolve faster; early-error handling preserved

Patch Changes

• beaecb3: fix(provider/openai): resolve responses doStream at response.in_progress instead of first output token

  The early-stream-error peek treated response.in_progress as an unknown chunk, so doStream did not resolve until the first output item arrived — delaying stream availability (and downstream TTFB for proxies/gateways) by the model's full time-to-first-token. response.in_progress is now modeled in the chunk schema and marks the request as accepted: the peek keeps watching for error frames for a short grace window (50ms) so quota/rate-limit errors flushed alongside response.in_progress still throw as retryable APICallErrors, while healthy streams become available right after upstream acknowledges the request.
