feat(theme-home): 样式即数据 + 首页抽组件去重（5g T3/T4）

【T3 样式即数据】
- content/site/theme.yaml 九组白名单旋钮（accent 明暗两值 / radius_img /
  text_h1-h3 / prose_size_reading|tech / leading_reading|tech /
  space_3-6 / flow_p 与 flow_h2_post / dur）；--measure、断点、纸墨、
  code 配色按方案 §3.6 红线不开放
- src/lib/theme.ts：getTheme() 钳制 + 单调性校验（h1>h2>h3、
  space3<4<5<6 任一不满足整组回落默认）；themeVarsCss() 产出
  `:root:root{…}` 与 `[data-theme="dark"]:root:root{…}`，靠特异性压过
  tokens 的 :root，不依赖注入顺序
- BaseLayout head 内联 `<style is:inline set:html={themeStyle}>`：构建期
  静态、运行时零 JS 零请求
- scripts/build-perf/contrast-check.mjs 读产物断言正文/强调 × 亮暗四项
  ≥4.5:1，不达标 exit 1；build.sh 守卫挂载（[ -f ] 守卫先行）
  实测：默认 12.40/10.53/6.30/7.06 全过；负例 accent #cccccc → 1.61:1 exit 1
  两坑入档：tokens 的 --bg 是 3 位简写需归一化；选 tokens CSS 要用
  `--bg:#` 定义断言（includes('--bg') 会误命中 var(--bg-soft) 引用）
- 后台 theme 单例 17 字段全中文 hint + 取值范围（分组约束写进 hint）

【T4 首页去重与细化】
- 新增 src/components/pages/HomePage.astro 承接全部区块（名片区富文本
  tagline/subtitle/社交、公告、文章列表、最新影像、热力图、项目墙、
  心跳），locale 一统；en 轨吃 postsEn 译题映射、图库链走 /en/gallery/，
  心跳仍仅 zh（零回归）
- 两 index.astro 缩成 4 行薄壳，双份漂移隐患消除
- home.yaml 三字段：projectsLimit(1-99 夹取，缺省 6)、announcement
  （双语 markdown 走 renderRich，空则不渲染）、postsTracks（三轨开关，
  在 HomePage 内过滤而非改 PostList，守边界）

验证: 构建 48 页 exit 0；contrast-check 四项 PASS；E2E 37/37（快照口径）；
      实测 theme 变量内联、公告 markdown 粗体渲染、projectsLimit 限流、
      photo 轨关闭生效；验收数据已还原
