Replace WireGuard with Nebula for true mesh networking

Browse Source 
- Switch from WireGuard point-to-point to Nebula overlay network
- Certificate-based trust with single CA for cluster authentication
- True mesh networking - all nodes can communicate directly
- Simplified joining process with lighthouse-based discovery
- Network range: 192.168.100.0/24 (lighthouse at .1)
- Auto-downloads and installs Nebula binaries
- Maintains GlusterFS replication across mesh nodes

Note: Certificate distribution requires manual step for security
