Summary

Protect historically supported large HTTP responses against new SDK-side body, event, or line caps, following the guidance in openai-node#2433.

Add three sequential, offline public-client cases with synthetic 16 MiB + 1 character payloads: Responses JSON output_text, a final Responses SSE snapshot through ResponseAccumulator (including typed output parsing), and an asynchronous Chat Completions SSE delta through ChatCompletionAccumulator. Compare the complete content without printing large fixtures on failure; no live API requests or recordings are involved.

The fixture deliberately stays below Jackson's longstanding 20,000,000-character string limit, inherited with the Jackson upgrade in #7. This preserves the existing contract while detecting new 8/16 MiB restrictions. Its high memory use is intentional, not a new API maximum. Add agent guidance to keep these probes and review any new rejection limits explicitly.

No production limits, dependencies, generated code, or custom-code budgets change.
