refactor: v2.0 全量重构 — TypeScript + React + Zustand + IndexedDB

技术栈升级:
- JavaScript → TypeScript 5.6(全量类型安全)
- 原生 DOM → React 18(函数组件 + Hooks)
- 全局变量 → Zustand 5(轻量状态管理)
- localStorage → IndexedDB / Dexie.js 4(大容量、异步、索引)
- marked.js → unified / remark / rehype(插件化渲染管线)
- 无打包 → electron-vite 3(HMR 热更新)
- 纯 CSS → CSS Variables + CSS Modules

新增功能:
- 标签页状态 IndexedDB 持久化(关闭后可恢复)
- 最近打开文件列表
- 大文件虚拟化行号(>2000 行)
- 搜索高亮二分查找优化 O(log N)
- rehype-sanitize HTML 安全过滤

文件结构:
- 7 个源文件 → 51 个模块化文件
- src/main/     主进程(6 文件)
- src/preload/  预加载(1 文件)
- src/renderer/ 渲染进程(42 文件:组件/hooks/stores/lib/db/types/styles)
- src/shared/   共享类型(2 文件)

构建验证:
- TypeScript 检查零错误
- electron-vite build 成功
- 产物:main 15kB + preload 2kB + renderer 1.5MB
