The edge: per-IP TCP/UDP/HTTP/HTTPS/TLS listeners with port ranges and PROXY
protocol, WireGuard tunnel endpoint, logins in front of web ports (built-in
proxy or Traefik), health checks and failover, and mail egress with DKIM
signing and MTA-STS. Split out of the original single repository; depends on
Reef for the shared types.
