feat(assist): enhance WebSocket session persistence

Add session extraction from peerId parameter for better WebSocket
connection stability. This improves assist session routing by:

- Extracting sessionID from peerId parameter using regex
- Setting upstream hash-by to use the extracted session ID
- Adding debug headers to monitor session routing

TODO: Convert this to map
