perf(comments): 评论加载提速 + 骨架屏 + 友链弹窗 pjax 修复 + toast 统一 Message.js

优化:
- initArtalk 加节点级幂等守卫(mount.__atkInited,失败回滚),
  消除 artalk.html/mypjax 多入口导致的 4× comments + 4× pv 重复请求
- fetch 包装层对无 body 的 GET/HEAD 去掉多余 content-type,
  消掉 Artalk 对 GET /comments 的 CORS 预检(按完整 URL 缓存,
  每篇文章都重付一次 RTT)。实测评论列表 +1150~1565ms → +626ms

修复:
- 评论列表骨架屏改注入 .atk-list-body(原骨架在 #Comments 内,
  被 Artalk.init 清空),list-loaded/故障/12s 兜底移除
- 友链申请弹窗抽成 modules/friendlink.js 进 page-only bundle
  (原内联脚本在 #pjax-container 外,pjax 后 flApplyOpenModal 未定义)
- toast 统一走本地化 Message.js/Qmsg 适配层(保留 window.Toast/showToast 旧 API)

文档:
- README / 架构总览 更新;新增 评论加载优化方案.md

/**
* 友链自助申请弹窗
*
* 为什么独立成模块(而不是留在 layouts/page/comment.html 的内联 <script>):
* 那段脚本写在 #pjax-container 外面,PJAX 只换容器内容、不会重新执行它 ——
* 用户从首页 PJAX 进留言页时 window.flApplyOpenModal 根本没定义,
* 「申请友链」卡片点了没反应;直接刷新(整页加载)才正常。抽到
* page-only bundle 里随 PJAX 加载,两种进入方式行为一致。
*
* 幂等性:弹窗节点挂 document.body(跨 PJAX 存活),buildModal 二次调用直接复用;
* 事件监听只在首次构建时挂,不会重复注册。
