v0.2.0: 全面代码质量优化

- ESLint flat config + Prettier + EditorConfig - Markdown处理器LRU缓存 - Zustand选择器优化减少重渲染 - CodeMirror Compartment主题热切换 - Preview防抖(150ms) + IndexedDB去抖(500ms) - 组件拆分: App.tsx 310→104行, Sidebar.tsx 244→90行 - 统一错误处理 errorHandler.ts - ConfirmDialog替代原生confirm - LoadingSpinner加载状态 - Toast多条堆叠+类型区分 - 可访问性增强(ARIA属性、键盘导航) - Vitest测试框架(78个测试用例) - Git hooks(husky + lint-staged) - 项目文档(README.md, CONTRIBUTING.md)
