优化: 工程实体化(description/stack/status)+ 概览工程列表

- project_modules 加 description/status 列(V40 迁移,stack V34 已有)+ models/repo/INSERT/UPDATE/SELECT 映射

- FileExplorer 工程 CRUD 弹窗加 description(textarea)/stack(input)/status(select)输入,工程有完整身份

- ProjectDetail 概览工程列表升级:name+status badge+path + description 段(2行省略)+ stack tag

- 老工程兼容(None=active),update 部分更新语义,status 归一(active/archived)
