andreasandClaude Sonnet 5.5 11d3fccf75 nftables: don't masquerade traffic leaving via ZeroTier
Hosts on the van LAN were all NATed to the router's ZT address when
reaching ZeroTier peers, hiding real source IPs from logs and
source-based firewall rules. Exclude ztuga7c2kh alongside br0.

# van-router NAT — masquerade LAN out whatever the WAN of the moment is
# (anything that is NOT the LAN bridge br0: ethernet/Starlink, wifi, future 4G).
# ZeroTier (ztuga7c2kh) is excluded too: it is a routed overlay, so van hosts keep
# their real 10.42.x source addresses there instead of all appearing as the van's ZT IP.
