Pull request overview
Allows users to extend the file extensions recognized as Code or Video, so that file types not present in the hard-coded Rust mapping can be previewed. The Video custom-extension editor is gated on useLocalFfmpeg since native decoding of non-standard formats requires ffmpeg transcoding.
Changes:
- Extend
get_file_info()withcustom_code_exts/custom_video_extsslices that act as a fallback after the built-in extension map. - Read
customCodeExtensions/customVideoExtensionsfrom theconfig.datastore insidepreview_file()and forward them toget_file_info(). - Add UI in
settings.vueto add/remove custom code and video extensions (tag-list + input), persist them to the store, and disable the video editor when ffmpeg is not enabled.

| File | Description |
|---|---|
| src-tauri/src/utils/mod.rs | Adds two extra parameters to get_file_info and falls back to user-defined extension lists when the built-in map misses. |
| src-tauri/src/preview.rs | Imports StoreExt, reads the two custom extension lists from config.data, and passes them to get_file_info. |
| src/views/settings.vue | Adds new settings sections (and CSS) for managing custom Code/Video extensions, with ffmpeg gating on the video side. |

Code 和 Video 类型的支持格式硬编码在 Rust 映射表中，用户无法扩展。Video 自定义格式需要 ffmpeg 转码才有意义，因此编辑入口应在 ffmpeg 启用后才开放。
后端（Rust）
utils/mod.rs：get_file_info()新增custom_code_exts/custom_video_exts参数，文件类型检测先匹配内置映射表，未命中时再检查用户自定义扩展名（自定义列表一次性小写化后比较，避免循环分配）preview.rs：引入StoreExt，在preview_file()中从config.datastore 读取customCodeExtensions/customVideoExtensions，传入get_file_info()；store 不可用时降级为空数组前端（Vue）
settings.vue：useLocalFfmpeg为false时输入框和按钮禁用，addVideoExt()内部同样做状态守卫自定义扩展名在用户输入时统一
toLowerCase()+ 去除前缀.后存储，后端读取后直接与已小写化的文件扩展名做字符串相等比较。
