Nick Hollon 803a268b39 feat(langgraph): add streamV2 infrastructure with unified transformer extensions

Adds the stream v2 protocol layer: StreamMux, EventLog, StreamTransformer
protocol, built-in ValuesTransformer/MessagesTransformer, StreamChannel,
ChatModelStream, GraphRunStream/AsyncGraphRunStream, and StreamingHandler.

Transformers use a unified name/value interface so built-in and user
transformers are exposed through the same extensions mechanism. Sync
projections (.values, .messages, extensions) all use _PumpDrivenLog for
consistent lazy pump-driven iteration.

Includes StreamProtocolMessagesHandler for converting LangChain message
chunks to protocol events (message-start, content-block-delta, etc.)
and wires it into Pregel.stream()/astream() via a config flag.
