## 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.
