feat: 新增文章阅读量计数(已登录去重 + 访客防刷)
- Post 模型新增 ViewsCount 冗余计数字段 - 新建 PostReadLog 表(user_id + post_id 唯一索引),已登录用户每篇文章只计一次 - 新建 PostGuestReadLog 表(visitor_id + post_id 唯一索引),访客基于 Cookie 标识去重 - Repository 层新增 RecordRead / RecordGuestRead / IncrementViewsCount - Service 层编排去重-计数逻辑,计数失败不影响页面渲染 - Controller 层 ShowPage + ShowAPI 触发计数,仅 approved 状态生效 - 双层防刷:唯一索引去重 + 2 秒冷却间隔 - 访客 Cookie (visitor_id) 基于 crypto/rand 生成,30 天有效期
