VLAN tagging: incusos-proxmox now reads optional `vlan` key from
proxmox.yaml and lab configs, appending `tag=N` to the VM NIC spec
in both SSH and API creation paths. Tested manually on VMID 850 —
VM received IP in 192.168.100.0/22 (Homelab VLAN). VLAN tag is
Proxmox-level only; IncusOS and Incus instances are unaware of it.
Networking guide: comprehensive tutorial covering bridge networking,
OVN overlay setup on IncusOS (services disabled by default, must
enable via REST API), cross-node connectivity, isolation, ACLs,
peering, load balancers, forwards, and DNS. All scenarios tested
on a 4-node OC-managed cluster.
