BasePlayerStrategy class abstract

策略基类，自动管理 ValueNotifier 监听的订阅与清理

继承此类后，只需在 onStart 中调用 listen 订阅 notifier， 框架会在 onStop 时自动取消所有订阅，防止内存泄漏。

Base class for strategies with automatic listener lifecycle management.

Subclasses call listen in onStart to subscribe to notifiers. All subscriptions are automatically cleaned up in onStop.
