fix(home): Top12 出道位接 /api/ranking 显示真实票数

- 首页 Top12Bar 之前只读 zustand store(初始 0 票),未登录访客永远看到"Awaiting Votes"
- 现在和 /ranking 页一样用 useRanking 30s 轮询,merge 服务端票数到本地 store(取 max)
- 与本地乐观投票兼容,投票后立即可见

bump to v0.3.2

+## v0.3.2 · 2026-05-15 · 修复:首页 Top12 出道位空着,排行榜却有数据
+
+**Commit 信息**
+- 完整 diff: [v0.3.1...v0.3.2](https://gitea.airlabs.art/zyc/UI-UX/compare/v0.3.1...v0.3.2)
+
+**改了什么**
+- 首页 Top12 出道位现在能显示真实票数(此前一直显示"Awaiting Votes")
+
+**根因**
+- 首页 Top12Bar 之前只读前端 zustand store 的 `artists`,store 初始来自 mock-data(36 人全部 0 票),只有**当前浏览器用户自己投票时**才会更新
+- 排行榜 `/ranking` 走 `/api/ranking` 直接读 DB,所以有真实票数
+- 未登录访客访问首页 → store 全 0 票 → `top12 = filter(votes > 0)` 空 → 显示"Awaiting Votes"
+
+**技术修复**
+- `src/app/page.tsx` 加 `useRanking({ pollInterval: 30_000 })`,30 秒轮询 `/api/ranking`
+- 用 `useMemo` 合并 `storeArtists`(本地乐观投票)+ API 票数(取 max),重新排序赋 rank
+- 与 `/ranking` 页面用同样的 merge 策略,保证两处票数视图一致
+
+**风险 / 已知问题**
+- 首页和排行榜各自跑一个 `useRanking` 实例,会产生两个独立轮询请求。后续可以提到 layout 层共享,但当前 36 行查询很轻,先这样
