refactor: 基于 upstream/Erotica 重新整合本地功能（来源选择/合并详情/计数/窗口/首页）

将本地在 upstream !408（已安装应用合并+统计）之上的后续改动重新整合到最新 upstream/Erotica：
- 已安装应用：卸载/打开按 APM/Spark 来源选择；计数总数=APM+Spark 包数（双来源计为独立包）
- 查看详情：已安装页复用所有应用页合并详情视图（单来源优先已装类型，双来源自动模式）
- 窗口：恢复阈值改为 1600x900，过大回退默认尺寸并居中，不自动最大化
- 首页推荐：致谢卡片移至其他内容下方，加大标题/卡片/致谢间距
- 隐藏排行榜/荣耀榜侧栏入口（代码保留，v-if=false）
- 新增 scripts/test-build.sh 测试打包脚本（版本末段+1 加 -test）并更新 AGENTS.md

冲突文件（index.ts/App.vue/InstalledAppsModal.vue）均取本地完整实现（为上游版本的超集）。
