/**
 * 双协议网络前置:按 PROTO 切手机蓝牙/WiFi，用于必测项控制用例的 BLE/WiFi 两种模式。
 *
 * - ble  模式: 开蓝牙、关 WiFi  → app 走 BLE 直连
 * - wifi 模式: 关蓝牙、开 WiFi  → app 走 WiFi/云
 *
 * 平台能力(已在三星真机实测):
 * - Android WiFi : adb `svc wifi enable/disable` 可行(dumpsys 实测真关/开)
 * - Android 蓝牙 : adb `svc bluetooth` 被新系统禁用(exit 137)、`cmd bluetooth_manager` 无实现、
 *                  `settings put bluetooth_on` 不动 radio → 改为 `am start 蓝牙设置` + 点 switch_widget(实测可切 ON↔BLE_ON)
 * - iOS         : 无公开 API,走系统设置(com.apple.Preferences)UI;locator 需 iOS 真机校准
