更新12个教务系统并优化项目大小

主要更新：
- 更新所有12个产业的教务系统数据和功能
- 删除所有 node_modules 文件夹（节省3.7GB）
- 删除所有 .yoyo 缓存文件夹（节省1.2GB）
- 删除所有 dist 构建文件（节省55MB）

项目优化：
- 项目大小从 8.1GB 减少到 3.2GB（节省60%空间）
- 保留完整的源代码和配置文件
- .gitignore 已配置，防止再次提交大文件

启动脚本：
- start-industry.sh/bat/ps1 脚本会自动检测并安装依赖
- 首次启动时自动运行 npm install
- 支持单个或批量启动产业系统
