需求 2.5.1 要求记录用户管理操作，先落表结构： - operation_logs 表：冗余 username 保证账号删除后仍可追溯， user_id 外键 ON DELETE SET NULL，success 默认 '0' 与 login_logs 口径一致 - 截断常量（USERNAME/ERROR_MESSAGE/REQUEST_DATA）集中定义，供写入方引用 - 修复既有 V1 迁移与迁移模板的 downgrade：索引是外键唯一支撑索引， 先 drop_index 会报 errno 1553，改为只 drop_table - 同步 db/migration/V2 与 init-dev.sql，迁移版本号更新为 a45a8087831b Co-Authored-By: Claude Code <noreply@anthropic.com>
