Zhou Weidong 3e2d6a06d9 perf(playback): 观看进度上报异步化(Redis write-behind 批量落库)
- POST /app/watch/progress 只写 Redis 缓冲立即返回(p95 75ms→2ms),
  WatchProgressFlusher 每 2s 把 watch:pg:dirty 队列按身份合并批量 UPSERT,
  Redis 异常自动回退同步写库,接口契约不变
- 读接口用缓冲覆盖 DB 行保证读己之写;Caffeine 缓存剧集校验免去上报路径两条 DB 查询
- 落库按「新增进度/新增流水/更新行」分组攒批(MyBatis BATCH 只合并连续同形状语句),
  配合 reWriteBatchedInserts 多值 INSERT,12.4 万积压 45 秒消化完,
  1650 QPS 持续压测队列稳态归零
