M1 回合制战斗架构收敛与 1v1 攻击闭环：BattleRuntime 内核、组件唯一入口、UI 数据驱动与 EditMode 测试

- 删除中间契约（BattleStartRequest/BattlePlayerInput/BattleReturnPlan/桥接与策略接口/FlowState），收敛为 BattleViewState/BattleStep/一层 BattleEvent
- 新增内部 BattleRuntime/BattleUnit/BattleStatus 共享上下文；TurnBattleComponent 成为唯一外部入口，吸收启动/暂停/回写职责
- 内核支持 1v1 攻击闭环：效果公式、HP/MP 钳制、阵亡、Victory/TotalDefeat、敌人随机决策；敌人行动间歇 0.6s 由组件协程编排并经 StepListener 推送
- UI：玩家卡片/敌人槽/回合槽按战局重建，图标配置驱动（含新增 EnemyConfig.Icon），每轮刷新一次 TurnSlots 且轮内只移动高亮
- 新增 Tests 程序集 + InternalsVisibleTo，25 个 BattleRuntime 纯逻辑用例全部通过
