feat(geek): 极客层 P0 四件套——键盘/构建透明/页面转场/项目墙

- Keyboard：? 帮助浮层 + t 明暗 + g-chords 导航（300ms 缓冲，输入域旁路）；
  路由表经 data-routes 注入（module 脚本 currentScript 为 null 的坑）
- BuildInfo：vite.define 四重回退注入 commit/时间，hash 链到 gitea
- ClientRouter 页面转场（reduced-motion 降级在 global.css 总闸）
- ProjectWall：构建时双源拉取（gitea+github）置顶排序+缓存兜底，零运行时 JS
- Header 补主题可视切换钮：键盘 t 的触屏等价物（同 key 同逻辑）

验证: pnpm astro build exit 0；dist 标记 built from×2/kbd-help×4/
      view-transition×2； astro check 未跑（无类型错误构建期可证伪面有限）
