docs(blog): 补全《20分钟搓了个 VSCode 插件》站内版细节并对齐外部原文

[Copilot]

• 分析评审意见：需要完整从知乎拉取文章内容，仿照其他博文格式覆盖本地
• 调查网络访问：zhuanlan.zhihu.com 及图片 CDN (picx.zhimg.com 等) 在此沙箱环境中 DNS 完全不可达
• 尝试多种替代途径：curl / Python / Playwright MCP browser / Google cache / Wayback Machine — 全部被 DNS 阻断
• 请作者提供知乎原文截图文件（或在 GitHub 上传），以便本地化图片
• 用提供的图片 + 正确格式重写 index.md

@copilot 原文的图片需要在这里本地加载，请导入到这边

@copilot 完全从 知乎将文档拿来下， 仿照其他博文，覆盖本地的

@copilot 完全从 知乎将文档拿来下， 仿照其他博文，覆盖本地的

此沙箱环境的网络防火墙完全屏蔽了 zhuanlan.zhihu.com 及其图片 CDN（picx.zhimg.com 等），DNS 均无法解析，也无法通过 Google 缓存、Wayback Machine 等途径绕行，所以无法自动拉取原文和图片。

如需完整复现知乎原文，请选择以下方式之一：

1. 直接上传截图：把原文截图作为文件上传到本 PR（GitHub 会托管在 user-images.githubusercontent.com，我能直接下载）；我来按其他博文的格式（本地化图片 + 完整正文）重写 index.md。
2. 提供原文文本：把知乎正文的 Markdown/纯文本粘贴到评论区，我来整理格式并补充图片引用占位符。

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
