refactor 3:

- EnemyManager.cs 不再计算 droppedCoin / droppedGold / baseDamage，只在敌人隐藏完成后区分“击杀”还是“非击杀到家”，并把 DREnemy 上报给 CombatScheduler。
- CombatScheduler.cs 新增统一入口：
  - OnEnemyDefeated(DREnemy enemy)：通过 EnemyDropResolver 解析掉落，再调用 CombatInRunResourceManager 入账，并按结果决定是否触发局外掉落判定。
  - OnEnemyReachedBase(DREnemy enemy)：从 enemy.BaseDamage 解析伤害，再统一扣减基地血量。
