新手引导视频:运营后台上传 MP4(上限 100MB,魔数校验只认 ISO BMFF), App 端在领券等候浮层前 N 次以引导视频替代广告。新增 guide_video 的 model/schema/repository/router(App 侧 + 后台侧)与播放记录表迁移。 美团券:首页「销量最高 / 智能推荐」两个 tab 改游标分页,配套两条 (city_id, dedup_key, 排序键 DESC) 复合索引,让 Postgres 顺着索引流式 去重,免掉每翻一页重排整城券的开销。美团 CPS client 在 lifespan 预热 并在关闭时释放连接池。 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

配置(开关 / 视频地址 / 次数 / 金币)复用既有 app_config 表,无需建表。
