- Link down/switch edges now softDisconnect() every started slot instead of disconnect(). The full stop could wait forever for a DISCONNECTED event on the Core 0 MQTT task, and it destroyed and recreated every slot's esp-mqtt task on each Wi-Fi drop, where the bridge previously stopped none (measured: 62 s deauth, five slots, zero stops). softDisconnect() is bounded and keeps the task; reconnectSlotClient() then calls reconnect() on the new route. Rename the transition action to disconnect_started_slots to match. - Ethernet no-IP recovery and init retries rebuild the CH390 netif, so they now run inside the route-switch mutation gate. An OTA/WebConfig lock taken after maintain() samples the lock count can no longer have the interface torn down underneath it.
