feat(viewer): likes, bubbles, visit reporting and hot sorting
Task 10 viewer 互动化: - 点赞:useLikes 批次状态机(500ms 防抖 / 5 次满额即冲 / 失败同 batchId 退避重试 3 次后回滚丢弃),乐观计数 + 服务端 total 权威校准 (countVersion 单调),大图与格子双入口; - WS 实时:RealtimeClient 纯状态机(半频心跳、指数退避重连、三败降级、 重连成功 resync 第 1 页重取),消息路由器做 likes.burst 自身过滤 (originBatchIds 求交)、隐藏页暂停与减少动画下仅校准不出气泡; photo.hidden/deleted 即时移出序列并回退邻居大图;降级后 8s 轮询接管; - 浏览上报:visitorId 跨标签 BroadcastChannel first-writer-wins 协调, 可见时上报、requestId 持久幂等、网络失败指数重试; - 排序:最新/热门 chips(热门走 ov 冷快照),大图打开期间禁用切换; 顶栏「减少动画」偏好开关; - 契约包新增 ./realtime 子路径出口(浏览器面不可引桶出口——其连带 internal-sync 的 node:crypto 会被 Vite 外置化致整页崩溃); - e2e 注入钩子 __viewerWsUrl/__viewerWsRetryBaseMs/__viewerRealtimePollMs/ __viewerBubbleMs 与 .activity[data-connection] 连接态锚。 vitest:viewer 105(新增 36:likes 批次 8、visitor 协调 5、上报门控 4、 路由 8、WS 状态机 7、排序 4);Playwright:viewer 21(新增 likes.spec 7、 journey 补互动腿断言)。 Co-Authored-By: Claude Code <noreply@anthropic.com>
