What
The client's SSE (server-sent events) streaming transport now calls a new onUserFrameReceived(uuid, rawPayload) callback whenever it receives a frame whose payload type is "user" and that carries a string UUID, before it passes the data on to the normal data handler.
Why
This lets other parts of Claude Code react specifically to incoming user-message frames and their identifiers as they stream in, rather than only handling them generically alongside every other frame type.
