feat: ignore字体集的生成文件，并在编译时自动生成

[M1LKT]

Modifications / 改动点

优化：MDI 图标字体按需裁剪并自动生成

将 subset-mdi-font.mjs 脚本从手动触发改为构建流程自动执行，同时排除生成文件避免污染仓库。

改动内容：

1. package.json

   • dev / build / build-stage / build-prod / preview 五个脚本均加入 node scripts/subset-mdi-font.mjs 前置步骤
   • 每次启动开发服务器或构建时，自动扫描源码中使用的 mdi-* 图标，裁剪字体文件并输出到 src/assets/mdi-subset/

2. .gitignore

   • 新增 src/assets/mdi-subset/ 规则，忽略脚本生成的 woff2 / woff / css 文件

3. 仓库状态

   • 执行 git rm -r --cached src/assets/mdi-subset/ 将已追踪的字体文件移出暂存区，避免重复提交生成文件

效果：

• 每次 pnpm dev / pnpm build 时自动生成最新的图标子集，无需手动运行 subset-icons

• 生成文件不进入 git，仓库保持干净

• This is NOT a breaking change. / 这不是一个破坏性变更。

Screenshots or Test Results / 运行截图或测试结果

验证步骤：

1. 运行 pnpm dev，观察控制台输出是否包含字体裁剪日志：

2. 运行 `pnpm build`，确认构建流程包含字体生成步骤且最终产物中包含裁剪后的字体文件 3. 检查 git status，确认 `src/assets/mdi-subset/` 不出现在变更列表中

Summary by Sourcery

Automate generation of the MDI icon font subset during dashboard dev and build workflows and stop tracking the generated assets in version control.

New Features:

• Run the MDI subset generation script automatically before dashboard dev, build, and preview commands.

Enhancements:

• Exclude the generated MDI subset assets directory from git to keep the repository free of build artifacts.

Chores:

• Remove previously committed MDI subset CSS assets from the repository.

Hey - I've found 1 issue, and left some high level feedback:

• The subset-mdi-font.mjs invocation is duplicated across multiple scripts; consider extracting it into a separate npm script or using predev/prebuild lifecycle hooks to keep the scripts DRY and easier to maintain.
• Running subset-mdi-font.mjs before vite preview may be redundant if preview is only serving the build output; you might want to restrict font generation to dev and build-related scripts to avoid unnecessary work in preview.

**suggestion:** Avoid duplicating the subset-mdi invocation across multiple scripts by leveraging npm pre-scripts or a shared script.

The `node scripts/subset-mdi-font.mjs` call is now duplicated in several scripts (`dev`, `build*`, `preview`). To keep this DRY and easier to maintain, consider using npm lifecycle hooks (e.g. `prebuild`, `prebuild-stage`, etc.) or a shared script like `"subset-icons"` that other scripts invoke (e.g. `npm run subset-icons && vite ...`). This avoids inconsistent updates if the subset command changes later.

Code Review

This pull request automates the Material Design Icons (MDI) subset generation by integrating the generation script into the project's build and development workflows within package.json. It also updates .gitignore to exclude the generated assets. Feedback suggests that the dev script lacks Hot Module Replacement (HMR) for new icons, which may lead to confusion unless a Vite plugin is used or the server is restarted. Additionally, running the subset script during the preview command is identified as redundant since that command serves already built assets from the dist directory.

[gemini-code-assist]

在 dev 脚本中自动运行字体子集生成脚本虽然实现了自动化，但由于它只在开发服务器启动时执行一次，因此不支持热更新（HMR）。如果开发者在开发过程中新增了图标，这些图标将不会被包含在生成的子集中，直到手动重启开发服务器。这可能会导致开发时的困惑（如图标不显示）。建议在文档中明确说明此限制，或者考虑将其实现为 Vite 插件以监听文件变化并自动重新生成。
