Changelog

1.43.0

(feat): Expose Stream[T].LastRetryMs() on the SSE runtime, mirroring LastEventID(). It returns the most recently advertised retry: reconnection time in milliseconds (sticky per the SSE spec), so callers can read the directive even when the server sends it in its own frame with no data: — in which case the per-event StreamEvent.Retry is 0. The value persists across reconnects.
