Ben Duncan 88baf5e202 feat: direct bridge mode — prefer over macvlan when WAN NIC != SSH NIC ...

Auto-detect bridge topology: if a dedicated WAN NIC exists (not used for
SSH), add it directly to br-external instead of creating a macvlan.
Direct bridge enables distributed NAT (DNAT on VM's own chassis) and
eliminates macvlan workarounds (MAC alignment, gratuitous ARPs,
centralized NAT bottleneck).

- topology.go: bridge-mode-aware NAT and localnet port options
- vpcd.go: auto-detect bridge mode, skip MAC alignment for direct bridge
- setup-ovn.sh: --direct flag for physical NIC on br-external
- reset-dev-env.sh: SSH NIC detection via SSH_CONNECTION
