NFR-3: Network

• Polling works over the same TCP relay as all other operations (send_cmd)
• No new network architecture needed
• The relay does not need changes for this feature (client-side only)

NFR-4: Memory

• Message list can grow unbounded if the user never leaves the app
• Consider capping the in-memory message list to a reasonable limit (e.g., 200 messages) and truncating oldest when exceeded
• The UI should not crash or slow down with large message lists
