/**
 * withRemoveAutoStart — 移除应用退出后的自启动/关联启动行为
 * 
 * 整改 2.2.6 APP频繁自启动和关联启动（存在风险）
 * 
 * 问题：以下 SDK 注册了 BOOT_COMPLETED 等 intent-filter，
 * 导致设备重启时应用被自动唤醒：
 *   - expo.modules.taskManager.TaskBroadcastReceiver
 *   - expo.modules.notifications.service.NotificationsService
 *   - androidx.work.impl.background.systemalarm.RescheduleReceiver
 *   - androidx.work.impl.background.systemalarm.ConstraintProxy* (多个)
 * 
 * 本插件在 final manifest 合并阶段移除这些 intent-filter action，
 * 从根本上消除应用退出后的自启动行为。
