fix(presenter,app-iced): 「游戏在跑」挡在落 core 之前（M247 r2）

塔裁决：三个写操作在实例启动/运行时必须拒，判据不能只靠界面灰按钮 —— Windows 上是 os error 32 兜底，**Linux 上删一个正在跑的世界会成功**，那是在用户玩到一半时把存档删掉。 - host/dispatch.rs：`AppCommand::Saves` 与 `AppCommand::Mods` 同款，先查 `CoreHost::in_flight(&id)` 再把 `running` 传下去 - host/saves.rs::dispatch 增 `running`：为真时三个写操作**不 spawn、不碰盘**，直接回一条 `SavesFailureKind::GameRunning` 的结构化失败；读路径与「打开文件夹」不受影响 - dto：新增 `GameRunning` 类别（不折进 WriteFailed —— 那不是"写失败"，是"我们主动没写"） - i18n：「游戏正在运行（先退出再操作）」中英成对 + 金表同步 - 用例：在飞时三条写命令盘上指纹不变/世界还在/备份落点没建，且回 GameRunning；反向用例钉住闸门没有把写操作一并关死；UI 侧断言三种动词的主句都不出现「写盘失败」且不画重试 - 拆分（400 行）：host/saves.rs → host/saves/write.rs；两处测试各拆出 write 子模块 - SavesState 模块文档补「生命周期」表：draft / pending / confirm 谁写谁清、何时必须清，并把 confirm「取走即清」（连点两下不删两个）写成安全不变量 - 出图：ULL_SAVES_FIXTURE=running 一张（失败那句话的样子）
