Nuno Campos 322cea054c Fix astream_events modifying output format unexpectedly 
- (unrelated) use run_id passed in
- if using a graph as node in another graph ensure stream_mode for inner call is always values
- ensure langchain-core doesn't auto promote streamed dicts to addable dicts, which results in unexpected output (only) when calling astream_events
