- Changed cluster detection to use sorted node names as cluster key
- Global deduplication by node name prevents duplicates
- Works correctly when cluster servers have different IPs
- Changed logic to process ALL nodes from cluster, not just the first one
- Added processedClusterIPs set to avoid duplicate processing of cluster servers
- Now clusters show all nodes (pve1, pve2, pve3) instead of duplicating first node
- Fixed issue where node names were incorrect after node reconnection
