[aa2246740]

This stays open until 2026-10-27: the repo waits 7 days on dependency bumps (opened 2026-10-20), and katex 0.19 still needs the math tests before it can merge. Not merging now.

[aa2246740]

先关掉这个升级。阅读页的公式渲染照着 DeepSeek Harness 宿主的流程来做（src/client/markdown/katex.tsx），渲染出来的结构要和宿主原生 Markdown 一致，所以 katex 的版本要跟宿主走。宿主 Harness 0.2.0-rc.2 现在用的是 katex 0.16.47（^0.16.47）；0.17 到 0.19 有破坏性改动，比如 0.18.11 收紧了 strict 规则。等宿主升到 0.19，再和宿主一起跟进。

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
