/**
 * 积分规则引擎订阅器（插件侧接入示例）
 *
 * eventPrefix='Score' => onBefore() 监听 ScoreBefore、onAfter() 监听 ScoreAfter
 * 需在 info.php 的 events.subscribe 中声明本类（见 addon/demo/info.php）。
 *
 * 三种接入姿势：
 *   1. 注册自己的动作：ScoreService::registerAction()，后台「触发动作」下拉即可选到
 *   2. 改分/取消/注入规则：onBefore() 返回 int 或 ['value'=>n] 覆盖分值、
 *      false 或 ['cancel'=>true] 取消、['rules'=>[...]] 注入临时规则
 *   3. 发放后联动：onAfter() 拿到 rule/value/uid 做通知、成就、等级等
 *
 * 主动发放（不需要事件）：
 *   ScoreService::trigger('demo.checkin', $uid, ['date'=>date('Y-m-d')],
 *       ['source'=>'demo', 'source_id'=>'checkin-'.$uid.'-'.date('Ymd')]);
