+DNS Failover Monitor with Bot Start/Stop (IMPROVED Dec 2025)
+
+CRITICAL IMPROVEMENT: Secondary trading bot stays STOPPED until failover.
+This prevents dual-bot interference where both bots trade the same wallet.
+
+Failover sequence:
+1. Detect primary failure (3 consecutive checks, ~90 seconds)
+2. Create DEMOTED flag on primary (prevent split-brain)
+3. Promote secondary database to read-write
+4. Update DNS to secondary IP
+5. START secondary trading bot <-- NEW!
+
+Failback sequence:
+1. Detect primary recovery
+2. STOP secondary trading bot <-- NEW!  
+3. Update DNS to primary IP
+4. Manual: Reconfigure old primary as secondary
