refactor 4:

- CombatWaitingForPhaseEndState.cs 不再调用旧的 PhaseLoopRuntime.ShouldEndCurrentPhase(...)，改为构造 PhaseEndConditionContext，再通过
PhaseEndConditionFactory.Create(currentPhase.EndType) 执行判定。
- PhaseLoopRuntime.cs 删除了旧的 phase 结束规则实现，现在只保留 phase 运行时数据管理，职责和架构文档一致。
- 为了让 BossDeadPhaseEndCondition 真正可用，我补了 boss 真值链路：
    - EnemyLifecycleTracker.cs 现在会跟踪存活 boss。
    - EnemyManager.cs 暴露 HasAliveBoss，并在 EntryType.Boss 刷怪时标记 boss 身份。
