feat: implement automatic ring positioning

- Remove manual --position parameter from CLI
- Add automatic optimal position calculation based on gap analysis
- Implement dynamic ring topology management
- Add position tracking and synchronization across nodes
- Add topology command for visual ring structure inspection
- Clean up unused variables and dead code
- Simplify node setup with automatic positioning
