Move is_connected() to the header as an inline method that returns a cached bool field. The previous implementation called wifi_sta_connect_status_() on every invocation, which makes SDK calls on ESP8266 (wifi_station_get_connect_status) and RP2040 (cyw43_wifi_link_status + WiFi.status), preventing inlining and adding overhead for the many callers that check it every loop iteration (network::is_connected, API server, MQTT, status sensor, etc.). The cached state is updated once per loop() after wifi_loop_() processes platform events. Internal call sites that need a live SDK query (STA_CONNECTED loss detection, RP2040 can_proceed) use the new is_connected_() private method directly.
