Johnathan Corgan 4a1d583653 fix(gateway): read conntrack over netlink when the proc file is absent
A kernel built without CONFIG_NF_CONNTRACK_PROCFS, such as Ubuntu's, has
no /proc/net/nf_conntrack. The gateway then counted zero sessions for
every mapping, so a mapping still carrying traffic was reclaimed on its
TTL and grace period alone.

When the proc file is absent, the gateway now dumps the IPv6 conntrack
table over NETLINK_NETFILTER, the request conntrack -L makes, and counts
each entry once per distinct destination, the same rule the proc parser
applies. The choice is made on every read, because the proc file appears
only once nf_conntrack is loaded. Any other proc error is still reported
without falling back. When both sources fail, the per-tick warning
carries the netlink error, and the startup line names both errors.

The dump uses netlink-packet-netfilter 0.3, the release built on the
netlink-packet-core 0.8 that rtnetlink already uses.

The gateway suite now expects the netlink source line when the
container has no proc file, and checks that the gateway counts the
session left by the HTTP request through the first virtual IP.

FIPS Documentation

FIPS (Free Internetworking Peering System) is a self-organizing encrypted mesh network built on Nostr identities, capable of operating over arbitrary transports — local networks, the public internet, Tor, Bluetooth, or point-to-point links — without central infrastructure.

With FIPS, your machine becomes a node in the mesh with a self-generated cryptographic identity. There are two ways to deploy it.

As an overlay on top of existing IP networks, FIPS lets your node reach any other FIPS node wherever it sits — behind a NAT, on a different ISP, on a phone over cellular, on a laptop with only Bluetooth in range, or behind a Tor onion. The mesh forwards IPv6 traffic transparently and end-to-end encrypted, with no central VPN concentrator or coordinating server.

From the ground up over raw Ethernet, WiFi, or Bluetooth, FIPS provides a complete permissionless network without any pre-existing IP infrastructure, ISP, or DNS. Any node that joins the link gets routable IPv6 addresses, peer discovery, and a path to every other node automatically.

Either way, existing networking software runs over it unchanged: SSH, HTTP servers, file transfer, anything IPv6-native works the same way it would on a local network.
