Menghuan1918 7f634866bf feat(editor): Markdown 预览内嵌 HTML 安全渲染 + 目录大纲(TOC)
宿主 MarkdownText 出于聊天安全把 raw HTML 按字面文本渲染,预览 GitHub
风格 README(徽章墙 div、details 折叠块内嵌 markdown、表格单元格内联
标签、video/picture)时全是源码文本。本次在不动渲染器的前提下:

- markdown-html.ts(纯函数):fence 感知切分器把文档切成 markdown/html
  段(CommonMark type-6 块级标签名单 + 注释段 + 空行终止);段内标签
  tokenizer 归约 open/close/html parts;全文档引用定义收集(每段追加
  保持 [text][id] 跨段语义)
- MarkdownHtml.tsx:DOMPurify 白名单消毒(显式禁 script/iframe/form
  等;a 强制 _blank+noopener;本地媒体 src 经 /sidebar/file 重写);
  MarkdownDocument 帧栈状态机让 <details> 跨段嵌套内部 markdown;
  MarkdownSegment 内联替换(MutationObserver 幂等 pass,把表格单元格
  等处标签文本消毒还原为元素,纯散文不误伤)
- md-toc.tsx:零高度 sticky 浮动目录按钮(≥3 标题)+ 弹出大纲,跳转
  平滑滚动 + 自动展开折叠 details + 高亮闪现。关键修复:子组件读父
  ref 在 React layout 阶段恒为 null(子先于父),改为经自身 bar ref
  的 parentElement 定位容器(jsdom 单测传预填 ref 掩盖了该 bug,仅
  真实挂载 e2e 抓到)
- 纯 markdown 文档走原单次解析路径零变化(现有 mermaid e2e 守卫一字
  不动);新增 readme-style.md 种子 + 探针(消毒渲染/嵌套/内联/TOC
  全链路);19 语言词典新增 toc 键;dompurify 提升为直接依赖(与
  mermaid 传递依赖去重单版本)

HuanLinOTO 751fb954a2 fix: address Copilot review (9 comments)
#1 GitView: hide/disable 'open in editor' for external linked worktrees
   (path outside session workspace is rejected by the fence); add
   isWithinWorkspace client helper for the gate.
#2 DiffTab: untracked diff read resolves against diff.repoRoot (child-repo
   paths are repo-root-relative, not cwd-relative); fs.read route threads
   selectedRepoOf into resolveGitPath so the host resolves the right base.
#3 GitView: chooseRepo handler mirrors chooseWorktree — clears status/
   history/log and bumps generation before async refresh, preventing stale
   rows from acting on the newly selected repository.
#4 git.ts: repoRoots/repoRoot compare roots via pathIdentity() (platform-
   aware) instead of raw includes(), fixing win32 forward/backslash
   mismatch that silently fell back to roots[0].
#5 markdown-images: mask fenced code blocks and inline code spans before
   rewriting; only rewrite reference definitions whose label is actually
   referenced by image syntax (not plain links). +3 tests.
#6 package.json: downgrade unrun ^0.3.1 → ^0.2.39 (0.3.x requires Node
   ^22.13, incompatible with declared engines >=20).
#7 market-manifest.spec: shell:true on win32 so execFileSync resolves the
   pnpm .cmd shim.
#8 smoke.spec: build html-route URL via encodeHtmlUrl() (production
   encoder) so the Windows drive separator is correct.
#9 index.ts git.worktrees route: thread selectedRepoOf so a workspace
   container's selected child repo's linked worktrees appear.

Lin bc6f1e129d fix(markdown): preview local/relative images in .md files
The shared MarkdownText only renders absolute http(s) images (relative
links are disabled for chat security), so a local image referenced by a
previewed markdown file - ![alt](./img.png), an absolute /cwd/img.png,
or a reference definition - showed only its alt text.

Rewrite such destinations into absolute /sidebar/file media URLs (with
the GUI origin prefix) so MarkdownText accepts them and the host media
route serves the bytes (still restricted to the session cwd). The
rewriter is a dependency-free pure helper (markdown-images.ts) with a
focused unit spec; TextEditor passes the rewritten preview text to both
the plain MarkdownText and the mermaid-lazy preview.
