fix: 标签策略启动初始化加固 + 已安装应用过滤/统计性能优化

- 标签优先显示策略 initTagPriorityStrategy 提到 App.vue onMounted 统一调用，
  消除组件挂载顺序导致先读内存默认 auto 的竞态窗口（AppDetailModal 移除重复调用）
- InstalledAppsModal 过滤逻辑合并为单次遍历（保留 hasOrigin 双来源语义）
- 统计 apm/spark/total 改为基于 searchFilteredApps 单次遍历
- canOpenDetail 补充业务含义注释与可读性变量
- 将 App.vue 重构的 9 个 composable 纳入版本管理
- 验证：vue-tsc 0 / eslint 0 / dpkg-buildpackage 打包 spark-store_5.2.1.24-test 成功

+/**
+ * useAppState —— 跨 composable 共享的全局原始响应式状态（单例）。
+ *
+ * 设计说明（避免循环依赖与重复实例化）：
+ * App.vue 原文件中的逻辑被拆分到多个 composable（useCatalog / useRanking /
+ * useAppDetail / useInstalledApps / useFavorites / useAccountSync / useDownloads）。
+ * 这些 composable 之间存在大量共享状态（apps / currentApp / installedApps /
+ * favorite* / 各类弹窗开关等）。若各自持有会出现多实例与状态不同步，并引发循环依赖。
+ *
+ * 故把"贯穿整个应用生命周期的全局原始状态"集中在本模块以单例形式导出，
+ * 所有 composable 与 App.vue 均从本模块取用同一份 ref 实例。
+ * 这与现有 global/authState.ts、global/storeConfig.ts 的单例风格一致。
+ *
+ * 本模块**只持有状态与极少量纯派生 computed**，不含任何业务逻辑/副作用，
+ * 确保拆分前后运行时行为完全一致（7 维度审计：功能/状态一致）。
+ *
+ * 注意：currentApp / currentAppSparkInstalled / currentAppApmInstalled 同时在
+ * storeConfig 中导出（供其它模块直接引用）。本模块从 storeConfig 再导出以保持单一实例。
