feat: implement ZeroTier exit gateway switcher Adds the luci-app-zt-gateway package: a LuCI app + rpcd/ucode backend + shell switch script that reconfigures which remote ZeroTier node acts as the internet exit gateway for WIBLAN clients (10.11.13.0/24). - Makefile (luci.mk, arch-independent) - UCI config skeleton with three sample gateways - rpcd ACL + menu entry - zt-gateway.uc rpcd backend exposing status / switch / health / drain_status / cancel_drain ubus methods - zt-gateway-switch shell script implementing force + graceful modes: * force: pre-flight ping, atomic route replace, conntrack flush, UCI/hotplug/rc.local persistence * graceful: dual-table drain using CONNMARK fwmark 0x100 at priority 99, background drain monitor with two-consecutive-zero completion and timeout-forced fallback to force - LuCI overview.js: gateway radio list, mode select, drain progress panel, cancel-drain button, health polling - Docker test harness (docker-compose + Dockerfile.router + router/gw entrypoints) exercising the switch script against real iproute2/iptables/conntrack on two simulated exit nodes Verified against the harness: force switch, graceful drain to natural completion, pre-flight blocking of unreachable gateways (force + graceful), and drain-timeout forced fallback. 2026-06-19 02:51:21 +05:30			`{`
