feat(品牌标识): 几何 K 图标(favicon/顶栏标记/theme-color) + 并行会话成果入库

## 品牌标识（本次会话）

起因：品牌此前没有任何图形标识 —— 唯一 favicon 是内联 data-URI 里的字母「A」，
那是 v2.0.0「Aurora Admin → Kole UI」改名漏掉的一处（PC 顶栏也是「A」，
移动端站已是「K」；移动端文档站则完全没有 favicon）。

- 几何：24 网格三个互不接触的笔画（竖 + 两斜），圆头描边；
  描边 2.25 → 16px 标签页尺寸下正好 1.5px = 规范原文「描边1.5px」
- 取色分两套（刻意）：favicon 硬编码品牌蓝/白（渲染在浏览器标签栏，不继承 kole-dark）；
  顶栏标记走 currentColor（实测暗色下自动转 rgb(20,22,28)）
- 新增 theme-color 双条（light #FFFFFF / dark #1C1F26，取 --kole-color-card-bg）
- 修 site/app.js hero 标语 KOLE ADMIN → KOLE UI（改名变形残留）
- 移动端 7 个模板补 favicon（此前计数 0）

验收：门禁 9 条全 OK（site-routing/site-routes/mobile-docs/mobile-site/isolation/
theme/nav/i18n/icons）；PC 回归 1464/1464 · 移动端 807/807，各连跑 8 次一致；
两端 favicon 405 字节逐字节一致；PC 站控制台错误 1→0。

## 并行会话成果（本次一并入库）

- 图标系统：2576 图标（TDesign/Element Plus，MIT）+ 11 端注入 + 5 个构建门禁工具
  + IconPreview 预览页 + ICON-SPEC.md 冻结规格
- 移动端平台：47 组件 × 6 端 + 文档站 53 页 + 隔离门禁
- PC 组件：103 个大后台组件 / 组件11 批次
- uni-app：PC 端试点 + 移动端端实现 + 真实编译验证

## 工程

- .gitignore 补 .scratch/ 与 .zcode-preexisting-*.txt（会话中间产物，实测 9.1MB，不入库）
- CHANGELOG 补品牌标识条目
- ROADMAP 登 S8-P4（品牌标识任务包 + og:image/apple-touch-icon 未做部分）
