perf(fonts): 字体子集化工具 + 汇文明朝单页 -40%（694KB→420KB）
- 新增 scripts/build-perf/subset-fonts.py：读字体 CSS 的 @font-face
（unicode-range）→ 扫内容收集实际用字 → 逐片交集裁切（pyftsubset
--flavor=woff2）→ 空片丢弃、重写 src 只留自产 woff2；支持
--chars-from/--chars-mode(all|headings)/--min-bytes/--merge
- 实测口径修正后结论（关键）：汇文明朝原 694KB/页 → 子集 420KB/页
（-40%，真收益，已接入）；站酷快乐体 163KB → 177KB（+9%，字跨片
分散致片数增加，**不启用**，保留原 @fontsource 源）
- merge 模式（合并单文件）标记实验性：fontTools.merge 对 CJK 切片字表
冲突敏感，实测产出异常，生产不用
- 三处实现坑入档：①hast 与 @fontsource CSS 一个 face 常带多格式
（woff2+woff），只替换首个 url 会残留失效引用（首版缺 58 个 .woff）
→ 改整段替换 src；②无 unicode-range 的 face 需按全范围处理，否则
原样保留同样残留引用；③裸跑 pyftsubset 需 fonttools+brotli
验证: pnpm astro build 48 页 exit 0；E2E 37/37；playwright 实测汇文
694KB→420KB 且字体栈生效（WF-Hwmc 命中）
