- uci-defaults: WG keygen, vps_gateway interface+zone+forwarding - heartbeat: sends wg_public_key, parses VPS config, calls vps-setup - parahub-vps-setup: new script for auto-configuring VPS tunnel with OTA bootstrap support and idempotent state tracking - parahub-mullvad: setup disables vps_gateway, remove re-enables it (fixes bug referencing non-existent vpn_tunnel interface) - parahub-gw-check: works with both vps_gateway and mullvad_local - sysupgrade.conf: preserves WG VPS keys across upgrades - build.sh: bump PARAHUB_BUILD to 4 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
