Adam Perry @ OpenAI 44dd77b71e Honor Retry-After headers in failed Responses events (#50418 )

## Why

Streamed `response.failed` events can carry retry advice in `response.error.headers`. Ignoring it loses server-provided delays or uses a conflicting delay from a rate-limit message.

## What changed

- Parse nested `Retry-After` headers using the existing HTTP header validation and retry parser, and preserve them for rate-limit, overload, and generic retryable failures.
- Prefer valid headers over rate-limit message advice, falling back to the message when the header is absent or invalid. Keep terminal error classifications unchanged.
- Reject unrepresentable plaintext retry durations without panicking.

## Testing

Add regression coverage for header precedence, validation, and terminal errors, plus retry-loop coverage for SSE sampling, remote compaction, and WebSocket failures.
