refactor: 多维度代码审查修复（安全/清理/类型）

- src/App.vue:
  - fetchAppFromStore 的 category/pkgname 路径参数 encodeURIComponent 编码（防路径穿越）
  - img_urls JSON.parse 增加 try/catch，解析失败回退空数组（两处）
  - onUnmounted 统一移除 hashchange/resize/keydown 及全部 IPC 监听，修复内存泄漏
  - 提取 createFallbackApp 消除 openDetail 重复回退构造
  - 收集并统一停止等待 loading 的一次性 watcher，闭环生命周期清理
- src/global/typedefinition.ts: 移除 CategoryInfo/HomeLink 宽泛索引签名，
  CategoryInfo 改用显式 extra 字段
- electron/main/backend/install-manager.ts: 清理冗余 eslint-disable 并修正缩进
  （remove-installed/check-installed 已通过 parseAppPayload 完成 pkgname 校验，无需改动）
