feat: 增加项目管理功能

引入 SQLite 数据库（Drizzle ORM + bun:sqlite），实现项目 CRUD 与归档/恢复/删除
生命周期管理，新增项目管理前端页面，migration 嵌入单文件构建产物保持部署体验。

- src/server/db: schema、connection、migration 执行器、项目数据访问层
- src/server/routes/projects: 7 个 API 端点（列表/创建/详情/更新/归档/恢复/删除）
- src/web: 项目管理页面（TDesign Table/Tabs/Dialog/Form），TanStack Query hooks
- scripts: 构建时嵌入 migration SQL，开发期独立 generate-migrations-data 脚本
- tests: 60 个后端测试 + 27 个前端测试，覆盖 DB/migration/API/路由/页面
- docs: 更新架构、后端、发布、配置、部署、使用文档
