新增 [Eis.Tools (line 1)](C:/Users/BI/Documents/EIS-dotnet/src/Eis.Tools/Program.cs:1)，支持 database init/reset/seed。

数据库维护、安全校验和事务逻辑位于 [DatabaseMaintenanceService.cs (line 1)](C:/Users/BI/Documents/EIS-dotnet/src/Eis.Infrastructure/Data/DatabaseMaintenanceService.cs:1)。内置完整演示数据：1200 名考生、10800 条成绩、2404 条招生记录。删除旧 import-test-data.mjs 和 reset-dev-database.mjs 运行入口。 Docker 镜像同时包含 Web 和 /app/tools/Eis.Tools.dll。 [package.json (line 11)](C:/Users/BI/Documents/EIS-dotnet/package.json:11) 原数据库命令已改为调用 .NET。新增统一发布脚本：[publish.ps1 (line 1)](C:/Users/BI/Documents/EIS-dotnet/scripts/publish.ps1:1)。
