- Add server module that orchestrates the full startup sequence:
parse config, init dynamic config, init shared state, bind health
check, bind admin socket, bind all listener ports, load TLS config,
start TCP listeners, start background tasks, signal readiness
- For each ListenerConfig: bind TCP listener, construct appropriate
ServerConfig (manual or ACME via TlsMode), create TlsAcceptor
- ConnectInfo<SocketAddr> populated from TcpStream::peer_addr() BEFORE
TLS wrapping via ConnectInfoService wrapper that inserts ConnectInfo
into request extensions for each connection
- Per-listener axum::Router instances sharing Arc<ProxyState> via State
- Fail-fast: if any bind or TLS load fails, exit with non-zero code
- All ports bound before any connections accepted
- /health endpoint available on HTTPS listener(s) as fallback
(proxy_router already includes /health route)
- sd_notify(READY=1) sent after all listeners started
- Use hyper_util for TLS connection serving with TowerToHyperService
and ConnectInfoService to bridge ConnectInfo from pre-TLS peer_addr
- Add sd-notify dependency for systemd readiness notification
