- Add 10-minute timeout to prevent infinite hangs in streaming loops - Silence 'ping' keepalive messages (log at debug level only) - Apply to both notification processing and synthesis streams - Prevents logs from being spammed with ping messages - Stream will break after 600 seconds if agent doesn't send 'done' This fixes the issue where streaming would hang indefinitely when agents get stuck or don't complete properly. 🐾 Generated with [Letta Code](https://letta.com) Co-Authored-By: Letta <noreply@letta.com>
