Pull request overview
This PR addresses a race where a DataTrackStream can receive an EOS signal before the data-track event listener is fully ready by also propagating EOS via the immediate DataTrackStreamReadResponse.
Changes:
- Add handling of optional EOS info returned directly in
DataTrackStream::read()responses. - Factor EOS-to-terminal-error conversion into a helper used by both event-driven and read-response paths.
- Add unit tests covering EOS delivered via
DataTrackStreamReadResponse(both normal EOS and subscribe-failure EOS).
