Report #50840

[architecture] Agent pauses execution to embed and write memories to the vector database synchronously

Decouple memory writes from the response loop using an asynchronous background task or event stream.

Journey Context:
Embedding text and writing to a vector DB takes tens to hundreds of milliseconds. If the agent waits for the memory write to complete before responding to the user, the perceived latency increases significantly. Since the user doesn't need the memory write to read the response, the agent should stream the response back and fire off the memory extraction/embedding as an async background job.
