新增能力：Web 与 Desktop 支持新建和保存 Markdown；桌面端注册 .md/.markdown 打开程序，支持单实例文件转交、自定义主题目录以及窗口位置、尺寸和最大化状态的延迟原子持久化与屏幕越界修正。 界面与兼容性：保留打开 Markdown 为独立主操作，将新建、保存和主题目录收纳到更多菜单；Web 移除本地素材目录入口并明确默认不支持本地素材；新文档默认使用一级标题或首行合法化生成文件名，可不保存直接导出 PDF。 渲染修复：图片、Mermaid 和 ECharts 按文档顺序串行执行媒体分页回填，每个媒体元素至多重排一次；图片以限宽后的高度作为缩放基准，只缩放媒体主体并保持标题尺寸；ECharts 冻结为 SVG 图片后参与统一分页。 示例与文档：默认示例仅保留一张网络图片，增加有效 Base64 横图、竖图、边界图片及多尺寸 Mermaid/ECharts；更新根 README、Desktop README、部署文档、四个 packages README、PROGRESS 和 AGENTS 发布规范；登记 v0.4.6 超链接导航问题。 部署与验证：构建并运行 yixiong/md-to-pdf:v0.4.5 正式镜像，Compose 健康且 PDF 冒烟无 Mermaid/ECharts 错误；生成 NSIS 安装包和免安装 ZIP，本机已升级到 NSIS v0.4.5 并清理旧 Squirrel 安装；202 项测试、类型检查、生产构建和 git diff --check 全部通过。 发布产物：Setup.exe SHA-256 9CBD6362E15AA745185805E753D5A7749434E0E142E6CE0F66463E6A19468F1D；ZIP SHA-256 97B2D44E72F626A3396E5AB5B330FFB7F9BECAF945A1707808C876940A82E850；当前 Windows 产物未配置代码签名。
