feat: 多班级版班级管理系统 v2.0
技术栈：Go (Gin + GORM) + PHP + MySQL 5.7 + Redis 主要功能： - 多班级完全隔离（class_id 贯穿全系统） - 后端从 Python FastAPI 重写为 Go Gin（端口 56789） - 超级管理员独立登录（env 配置路径，默认账密 admin/Admin123） - 科任老师/课代表新角色 - 课代表作业管理页面 - 排行榜分项排行（操行分/考勤/作业） - 角色加减分上下限由班主任配置 - 家长改密功能（可开关） - 班级角色按需开关 - 宿舍号格式：南0-000 - 周度/月度重置功能 - MySQL 5.7 兼容 - Nginx 反向代理部署 开发者: Canglan 版权归属: Sea Network Technology Studio 许可证: Apache License 2.0
