fix(runtime): 按参考主题硬切换为 loader/main/auto_fun 单一 DOM 生命周期

- 删除 AksrtFrontend registry/rehydrate 双路架构及 build/public.js 拼包入口，
  前台唯一初始路径为 PHP 本地栈（jQuery 1.9.1 → Bootstrap 3.4.1）
  → loader_js（_win/aksrtData 唯一注入）→ tbquire(['main']) → runtime/main.min.js
- window.auto_fun = debounce(z_auto_fun, 100) 为唯一重扫入口；所有模块改为
  执行一次 + off/on('auto_fun.aksrt-*') 命名空间重扫，data/class 标记幂等
- 局部更新协议统一：HTML 注入 → post_ajax.ed → auto_fun()；
  远程 modal → loaded.bs.modal → auto_fun()；JSON 成功 → zib_ajax.success
- 灯箱恢复 Miniimgbox/imgbox 唯一 owner（imgbox-container、a[data-imgbox]、
  imgbox_data），删除 AksrtLightbox/data-aksrt-lightbox 第二实现及 CSS/overlay，
  _win.imgbox* 重新接上 post-display 设置
- 死代码清理：runtime 下 11 组被自有实现替代的旧模块副本、无消费 vendored 库、
  顶层 grade.min.js、revenue.js、无调用方的 aksrt_get_win_runtime_config()，
  以及 loader 中 16 条死 mapping
- PHP 入队改为本地栈 + loader_js，routed/widget/submit 依赖统一换绑；
  用户卡片发布按钮恢复 nav_user_newposts_btn 设置门控
- 测试对齐：新增 frontend-lifecycle-contract，重写 navigation/lazyload/toast/
  auth-source/comment/page-display/post-visual 等断言为目标架构契约

验证：node --test widget-system+navigation 223 通过 0 失败；
构建脚本重建 main/imgbox min 与 CSS bundles；改动 PHP php -l、JS node --check
全部通过；git diff --check 干净；credits 重入 harness 通过。
