Consistent async streaming for Workflows

Deprecated stream_intermediate_steps in favor of stream_events

The stream_intermediate_steps setting is deprecated. Use stream_events for a single, consistent way to control streamed event emission across components, reducing configuration overhead and drift.

Explicit control over non-content events during streaming

Non-RunContent events (e.g., operational or summary signals) now emit only when stream_events=True. This reduces noise in streaming responses and ensures UIs receive only the events they opt into.

Faster runs with concurrent memory updates and richer end-of-run events

Memory updates now occur in a background thread, reducing latency for users and UIs. We’ve also added events for run content completion and session summaries to make end-of-stream handling more…
