Radical simplification — no more VPS data plane: - Delete parahub-vpn-tunnel init script (GRE6 no longer used) - Revert heartbeat to clean version (no tunnel_ip parsing) - Add parahub-gw-check: monitors WireGuard handshake, switches batman-adv gw_mode between server/client (cron every 2 min) - Update uci-defaults: remove vpn_tunnel zone/interface, start bumblebee as gw_mode=client (health check promotes to server) Guest internet now requires Mullvad — kill switch by design.
