release: v0.4.1 — MetonaEditor 0.1.10 升级与三主题系统

- chore: 升级 @metona-team/metona-editor 0.1.3 → 0.1.10
- feat: 三主题系统（亮色/暗色/暖色），循环切换
- feat: 应用颜色自动同步编辑器主题（MeEditor.themes.exportCSSVars）
- feat: 启用编辑器新功能（lineNumbers/autoBrackets/readOnly/autofocus/exportTool）
- refactor: 主题从 boolean darkMode 重构为 ThemeMode 枚举
- refactor: 插件注册改用字符串数组（与 demo 一致）
- refactor: 主题同步从手动 CSS 覆写改为 editor.setTheme() 实例 API
- refactor: Ctrl+S 双通道（编辑器 onSave + 全局兜底）+ 防重入锁
- style: 移除 variables.css 中硬编码 .dark 色值，改为 JS 动态驱动
- test: 更新 editorStore 测试覆盖新的 themeMode/cycleTheme

+### 编辑器架构
+
+MarkLite 使用 [MetonaEditor](https://git.metona.cn/MetonaTeam/MetonaEditor) v0.1.3 作为编辑器核心：
+
+- **三模式视图**（编辑 / 分屏 / 预览），由 MetonaEditor 内置工具栏切换
+- **渲染管线**：通过 `render` 钩子接入 unified/rehype 管线，处理图片路径修复和代码高亮
+- **插件**：searchReplace（搜索替换）+ imagePaste（粘贴图片）
+- **自动保存**：自定义 `useAutoSave` hook，通过 Electron IPC 保存到文件系统（非 localStorage）
+- **主题同步**：应用暗色模式与编辑器主题双向同步

+## 6. 编辑器架构 — MetonaEditor v0.1.3
 
-### 6.1 双编辑模式
+### 6.1 三模式视图
 
-- **编辑模式 (Milkdown)**：基于 ProseMirror 的 WYSIWYG Markdown 编辑器，支持格式化工具栏（粗体/斜体/删除线/标题/列表/引用/代码块/链接/图片/分割线）、搜索替换面板（含正则支持）、自动配对括号/引号、undo/redo
-- **源码模式 (SourceEditor)**：原生 textarea 控制 Markdown 原文，支持 Tab 缩进、Ctrl+B/I 快捷键
+- **编辑模式 (edit)**：纯文本编辑器，显示 Markdown 源码
+- **分屏模式 (split)**：左侧编辑、右侧实时预览，同步滚动
+- **预览模式 (preview)**：仅显示渲染后的 HTML
 
-两种模式共享同一 tabStore 数据源，可随时切换。
+MetonaEditor 内置模式切换工具栏，与应用层的 viewMode store 双向同步，切换时自动持久化到 IndexedDB。
 
-### 6.1.1 主题切换
+### 6.2 内置功能
 
-Milkdown 编辑器通过 CSS class（`milkdown-dark`）切换暗色主题，无需销毁重建 EditorView，
-切换标签时保持光标位置和选区。
+| 功能 | 说明 |
+|------|------|
+| 格式化工具栏 | bold / italic / strikethrough / underline / code / h1-h3 / quote / ul / ol / indent / outdent / link / image / table / hr |
+| 搜索替换 | Ctrl+F / Ctrl+H，支持正则、大小写敏感 |
+| 历史栈 | undo / redo，防抖合并，可配置上限 |
+| 主题 | light / dark / auto / warm，CSS 变量驱动 |
+| 国际化 | zh-CN / en-US 完整翻译 |
+| 全屏模式 | 编辑器全屏展示 |
 
-### 6.2 插件体系
+### 6.3 插件体系
+
+通过 `plugins` 配置数组安装 MetonaEditor 预设插件：
 
 | 插件 | 说明 |
 |------|------|
-| commonmark | 基础 Markdown 语法 |
-| gfm | GitHub Flavored Markdown（表格/任务列表/删除线等） |
-| history | undo/redo |
-| listener | 内容变更监听 |
-| indent | Tab 缩进 |
-| trailing | 尾随换行 |
-| clipboard | 剪贴板增强 |
-| searchPlugin (自研) | 搜索高亮装饰 |
-| autoPairPlugin (自研) | 自动配对括号/引号 |
+| searchReplace | Ctrl+F 查找、Ctrl+H 替换面板 |
+| imagePaste | Ctrl+V 粘贴剪贴板图片，自动转 base64 |
 
-### 6.3 滚动与选区持久化
+> 注：autoSave 插件仅支持 localStorage，而 MarkLite 需要文件系统保存（Electron IPC），因此使用自定义 useAutoSave hook。
 
-切换标签时自动保存/恢复：
-- 滚动位置 (`scrollTop`)
-- 光标选区 (`selectionStart`, `selectionEnd`)
+### 6.4 渲染管线集成
+
+通过 MetonaEditor 的 `render` 钩子接入 unified/rehype 管线，实现：
+
+- **相对路径图片解析**：将相对路径转换为 `file://` 绝对路径
+- **XSS 防护**：rehype-sanitize 过滤危险标签
+- **代码高亮**：rehype-highlight 语法高亮
+- **处理器缓存**：LRU 缓存（最多 20 个），按文件路径分桶

+
+### 6.5 主题切换
+
+MetonaEditor 的 CSS 样式通过 wrapper 元素上的 inline `--md-*` CSS 变量驱动。主题切换流程：
+
+1. `MeEditor.setTheme(dark/light)` — 更新 documentElement 全局变量 + localStorage
+2. 手动覆写 `.me-wrapper` 上的 inline CSS 变量（`style.setProperty`）
+3. 双向同步：应用工具栏暗色按钮 ⇄ 编辑器主题
+
+### 6.6 内容同步
+
+- **编辑 → 存储**：`onChange` 回调 → `updateTabContent` + `setModified`
+- **标签切换**：`setValue(content, { silent: true })` 静默更新，避免重复触发 onChange
+- **滚动持久化**：切换标签时通过 DOM 查询 `textarea` / `.me-preview` 保存/恢复滚动位置
