laoyang 3fcaf25c58 3.2.36 新增「自动头像」：按邮箱本地生成，14 套 CC0/MIT 风格可选 #5 
为没有头像的访客按邮箱确定性地生成一张 SVG 头像，替代 Gravatar
那个灰底"神秘人"（cn.gravatar.com 在国内已超时，不勾加速时头像
干脆是空白）。全程纯 PHP，零外网请求、零落盘。

后台「主题设置」新增「自动头像」复选框 + 风格列表：勾上之后才
出现 14 套风格，点一下即时换 16 格预览，保存后全站生效。

实现要点（都是踩出来的）：
- PRNG 必须与 DiceBear 9.x 逐位一致：xorshift + hashSeed 全程跑在
  JS 的 int32 语义里，PHP 64 位整数要逐步 i32() 归一；
  charCodeAt 按 UTF-16 码元取值，emoji 必须真做代理对拆分。
- pickComponent 有简繁两版：只有 glass/rings/shapes/thumbs 额外取
  三次整数（rotation/offsetX/offsetY）。给简版也补三次 ⇒ PRNG 多走
  3N 步 ⇒ 31 套里 27 套全错。编译期算 pc_has_ints 才治得住。
- 自带人类调色板：官方默认配色几乎全单值，30 个邮箱只出 2 种配色，
  那才是"默认头像丑"的真因，光换画风解决不了。
- 只收录 CC0/MIT（13 CC0 + 1 MIT），CC BY 那 13 套要求署名，一律不收——
  主题装给用户用，用户不会维护署名，收进来等于转嫁合规义务。

接入 get_avatar 的两个关键修正：
- 必须先看原 src 是不是 Gravatar 家族域名再决定是否替换。原先无条件
  替换会把媒体库头像、外链头像、别的插件处理过的 data: 头像一起盖掉。
- 必须删 srcset。只改 src 留着 srcset，浏览器优先用 srcset，
  生成的图根本不会被加载（现象是"代码明明换了，页面还是老样子"），
  且不能重建 <img> 标签（会丢掉评论头像 CSS 依赖的 class）。

后台三处必须这么做：
- body class 由 PHP 输出（admin_body_class），否则每次进设置页/保存后
  重载都会先显示风格列表再藏起来，闪一下。
- 事件监听 radio 的 change，不能监听 label 的 click —— label 会把
  click 转发给关联 input，冒泡回来再触发一次 ⇒ 同一风格发两次请求
  （实测 hits 2→4）。
- 首屏已渲染的 16 格写进 JS 缓存，否则点一圈回到默认风格会白请求一次。

不依赖任何可选扩展：不用 mbstring（未安装时 mb_substr 是 Fatal error，
整站白屏）、不用 gd/imagick。UTF-8 切分/截断/大写全部自己实现。
PHP 7.0 语法，PHP 8.5 下 E_ALL 无任何 warning。

验证：
- 14 套 × 6 种子 = 84 个用例与 DiceBear 官方 Node 输出逐字节一致，
  PHP 8.4 / 8.5 / 无 mbstring（php -n）三种环境均 84/0。
- 静态守卫 55/0；反向验证 17 项注入全部被捕获。
- 后台面板浏览器验证 26/0（显隐、几何、点选、缓存、连点、零报错）。
- 包内内容契约 24/0；包校验反向验证 6 项注入全部被捕获。
- 单次渲染稳态 0.047~0.105ms，峰值内存 2~4MB。
