feat(#10): add batch download settings and capabilities

- Introduced new batch download settings in the settings slice, allowing users to configure options for directory picking, streaming ZIP downloads, and blob ZIP downloads.
- Implemented a new general settings panel for managing batch download preferences.
- Added utility functions to handle directory selection and ZIP file creation.
- Updated the download logic to support multiple download modes based on user preferences.
- Enhanced documentation to reflect changes in batch download functionality.

### 批量下载约十首后失败 / 无法全部下载
Chromium 系浏览器会限制页面在短时间内通过程序触发的**多个**文件下载(常见表现为大约十个文件后静默中断,或提示「此网站正在尝试下载多个文件」)。
本站的「下载全部」会按「设定 → 通用设置 → 批量下载」中勾选的顺序尝试:
1. 选择输出目录,直接写入文件(推荐,Chrome / Edge)
2. 流式生成单个 ZIP 并保存
3. 在内存中生成 ZIP 后触发一次下载(兼容性最好)
若全部失败会弹出提示。大批量转换也可使用 [命令行版本](https://git.um-react.app/um/cli)。
### Via 等浏览器无法正常解密/下载
⚠️ 手机端浏览器支持有限,请使用最新版本的 Chrome 或 Firefox 官方浏览器。
