fix(vue): resolve the @ alias in Vue projects without Vue CLI

Only projects depending on @vue/cli-service got their webpack aliases passed to tsserver, so in a Vue CLI 2 (vue init webpack), custom webpack or Vite project without jsconfig.json, imports like import('@/views/index.vue') resolved to nothing. Such projects now get the aliases of their own webpack configuration (webpack.config.js, build/webpack.base.conf.js; a function or a list of configurations is evaluated too), else the @ -> src alias every Vue template sets up.

-OpenIDEA 把 IntelliJ IDEA 的使用方式（快捷键、工具窗口、随处搜索的习惯）带到一个以 Rust
-为核心的原生桌面应用里。
-
-编辑器、代码洞察、调试器、Git、终端、数据库客户端和 HTTP 客户端，支持 60 多种语言。
-提供 macOS、Windows 和 Linux 版本。
-
-## 性能对比
-
-在缓存已预热的情况下打开 [freqtrade](https://github.com/freqtrade/freqtrade)（Python，约 770 个文件），
-取 5 次运行的中位数：

-测试使用 `main` 分支的 OpenIDEA release 构建，以及默认设置和插件的 IDEA，环境为 Windows 11、
-32 核 AMD、62 GB 内存。IDEA 对 Python 的分析更深入，所以两边的“就绪”并不代表完成了同样多的工作。
-两者都以相同方式从外部测量：可以用 [`perf/compare`](perf/compare) 在自己的机器和项目上复现。
-
-## 插件
-
-插件可以添加操作、补全、快速修复、工具窗口、自定义编辑器、主题、文件图标和语言。插件以沙箱化的
-WebAssembly 组件运行；主题、图标主题和语言无需编写代码。
-
-在“设置 › 插件”中安装，或用 `openidea-plugin new` 创建自己的插件：参见
-[编写 OpenIDEA 插件](https://openidea.sh/zh/plugins)和[官方插件](plugins/official)。插件 API 目前仍是预览版。
