router.firewall.nat replaces the dnat/toPort/hairpin fields of the filter
rules. Filter rules gain natOnly, and may use wan with log and rate limit
in the web UI. The Firewall page edits the NAT table and can add the
matching allow rule. Settings schema 1 (migrations/1.jq) converts old
forwards.

lans.<n>.ipv6.address (a ULA /64) is assigned to the LAN, announced
with an explicit prefix (networkd only announces the delegated prefix
when prefix delegation is on) and advertised as RDNSS; Unbound listens
and answers on it. Checked at build time: valid IPv6 CIDR, /64, fc00::/7.
Covered by the onestick VM test (client SLAAC address, ping and DNS over
the ULA, RA captured on the wire), assertion cases and a unit test for
the /64 prefix helper.

- wan.ipv6.transport = "ppp": IPv6CP in pppd, router advertisements and
DHCPv6 prefix delegation on the PPP device, DHCPv6 accepted on the PPP
device, IPv6 MSS clamped to MTU-60. Allowed on a shared single-NIC
link. A build-time check requires a PPPoE uplink.
- IPv4 MSS clamping now only matches IPv4 packets.
- The example uses the new box's NIC name (enp2s0).
Covered by the onestick VM test (radvd and a minimal DHCPv6-PD
responder as the ISP) and assertion cases.

- Allow the WAN link to also carry LANs when the uplink is PPPoE on a
VLAN with IPv6 off; only the PPP device counts as an uplink then, so
LAN traffic can never match WAN rules.
- Add router.rollback: router-arm / router-confirm / router-rollback
plus `nix run .#deploy`, a commit-confirm deployment flow.
- Wait for the LAN devices instead of the uplink in networkd
wait-online, so an unplugged uplink cannot block boot or activation.
- Add examples/desktop (single NIC, PPPoE on VLAN 1001) as
nixosConfigurations.example, built as a flake check.
Covered by the onestick and rollback VM tests and new assertion cases.
