xfy 81682eb70e fix(post): 修复 hash 锚点跳转失效
内容异步加载(use_server_future)导致骨架屏阶段标题 DOM 缺失,浏览器原生
fragment-scroll 找不到目标留在顶部;刷新页面也因 SSR 出的是骨架屏而失效。

- 新增 __scrollToHash 全局入口(yggdrasil-core):内容挂载后解码
  location.hash(CJK 百分号编码 → 原始字符)并 scrollIntoView
- PostContent use_effect 末尾复用 invoke_optional_global 调用,标题
  DOM 已就绪时补一次滚动
- 标题加 scroll-margin-top: 6rem,避开 80px sticky header

点击 TOC/标题 hashtag 由原生 anchor + scroll-margin-top 覆盖,无需 JS。
