release: 发布 v0.6.1 DOCX 视觉一致性修复

新增通用 CSS 到 OOXML 翻译修复，统一字体、字距、精确行距、段落、列表、表格、引用、代码块与行内代码连续性，不引入按主题 ID 分支。

新增 MdTP Mono 并统一 Serif、Sans、Mono 三字体包的 Chromium 与 DOCX 使用链；字体声明、嵌入部件和 Word/WPS 实际采用均进入硬门禁。

重建封面整页及正文语义块视觉差分，14 套主题、纵横两个方向、五组页边距共 140 个真实场景全部通过，阻断失败和诊断失败均为零。

源码服务、Docker Web API 与实际安装 Desktop 的 red-briefing 导出均包含 5 个字体部件；Word/WPS 原生渲染和逐页复核通过。修复 Docker 构建上下文与运行层复用软链接，并完善 v0.6.1 版本、发行说明和发布归集。

验证：npm test（116 个文件、616 项测试）、npm run typecheck、npm run build、git diff --check 全部通过。Desktop 安装器与 ZIP、Docker v0.6.1 镜像已生成；Windows 产物仍为未签名内部发行。
