回归: 提交主题中的内联代码范围内的 `<...>` 仍会导致 PR 体解析失败,默认跳过一个组件版本(Manifest 模式)

This is a regression/incomplete fix of #1659 (fixed by #1661). HTML tags inside **inline code spans** in commit subjects are intentionally left unescaped by `htmlEscape()`, but they still break the PR-body re-parsing step, causing a component's release to be silently skipped.
