* docs(zh-cn): fix project-context syntax and wording
我将 project-context 文档中的提示块语法统一回项目规范的 `:::...:::` 形式，避免与文档风格约定不一致。
我同时把“在不同用户故事（story）间决策不一致”调整为“之间决策不一致”，提升中文表达的自然度与可读性。

* feat(i18n): add zh-cn locale support with Starlight routing
Reorganize Chinese translations from docs_cn/ into docs/zh-cn/
following Starlight's i18n content structure. Configure Starlight
with root locale (en, unprefixed) and zh-cn (/zh-cn/ prefix).
- Move 28 files from docs_cn/*_cn.md to docs/zh-cn/*.md
- Fix 21 internal links to remove _cn suffixes
- Add defaultLocale + locales config to astro.config.mjs
- Add .gitignore exception for docs/zh-cn/ (overrides z*/ rule)
- Language switcher activates automatically via existing Header
- hreflang tags auto-generated by Starlight on all pages
* feat(i18n): add zh-CN UI translations and sidebar labels
- Add website/src/content/i18n/zh-CN.json with Starlight UI strings
- Add sidebar group label translations (欢迎, 路线图, 教程, etc.)
- Register i18n collection in content config to fix deprecation warning
* fix(i18n): exclude 404 pages from sitemap
Custom 404 pages (root and zh-cn) were indexed as regular content in
the sitemap. Add a filter to the @astrojs/sitemap integration that
matches the /404 path segment precisely via regex on the URL pathname.
