Creates a StreamTransformer that groups messages channel events into
per-message ChatModelStream instances.
A new ChatModelStream is created on message-start and closed on
message-finish. Content-block events in between are forwarded to the
active stream. Only events whose namespace exactly matches path
are processed; child namespaces are ignored.
