v5.5.4: Add hardcoded seed nodes for automatic network mesh

- Hardcoded DNS3 (74.208.167.19), DNS2 (194.233.88.206), and Contabo (100.98.123.59) as fixed seeds
- Nodes will automatically connect to these on first run
- No manual addnode configuration needed
- Full mesh network connectivity built into the code
