Add interview-focused project brief and resume corrections

[Copilot]

Updated documentation to help recall project principles for interviews and aligned resume wording with actual implementation (multi-language hover-based Markdown rendering).

• Summary & Principles

  • Added INTERVIEW_BRIEF.md covering intro, tech stack (TS, VS Code HoverProvider/MarkdownString, esbuild, pnpm, ESLint, TS strict), parsing/rendering flow, and key highlights (15+ languages, lightweight heuristics, no Webview).
  • Clarified that parsing relies on language→comment-pattern mapping + heuristics (not AST/Decoration API/LRU).

• Resume Guidance

  • Provided corrected resume blurb and contrast against prior claims (AST/Decoration/LRU vs. current lightweight approach).

• Interview Prep

  • Listed likely interview questions (parsing trade-offs, multi-language extensibility, performance, testing).
  • Noted comment delimiter examples (""", <!-- -->) in the parsing sequence.

No code changes; documentation-only update.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• update.code.visualstudio.com
  • Triggering command: /usr/local/bin/node node /home/REDACTED/work/CommentMarkdownRender/CommentMarkdownRender/node_modules/.bin/../@vscode/test-cli/out/bin.mjs (dns block)

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)

Original prompt

我将要拿这项目去面试，我现在完全忘记了这个项目的原理,整理出一份针对这个项目的简介，技术栈，原理，解析过程，可能会问道的面试题
简历中这个项目描述如下

• 项目背景： 针对传统代码注释阅读体验差的问题，开发 VSCode 插件，支持在多种语言（JS/TS/Java等）注释中书写 Markdown 并通过悬浮窗实时渲染。
• 核心难点与实现：
• AST 解析与正则匹配： 并没有采用简单的正则全量替换，而是针对不同语言特性设计解析策略，精准提取注释块。
• 高性能渲染机制： 利用 VSCode Decoration API 实现轻量级渲染，配合 Debounce 防抖 与 LRU 缓存策略，确保在万行代码文件中滚动时无掉帧，内存占用极低。
• 多语言架构： 设计可插拔的 Provider 模式，便于快速扩展对新语言的支持，目前已支持主流 5+ 种编程语言。

校对上面的描述，并给出建议
