feat: 新增 compute_gateway、compute_poller、agent 模块，重构前端 dist

- 新增 backend/app/modules/compute_gateway（client/sync）计算网关模块
- 新增 backend/app/workers/compute_poller 计算轮询 worker
- 新增 compute/agent/process_manager 进程管理器
- 新增 scripts/ 脚本目录
- 更新 Docker 部署配置（app/compute/nginx）
- 更新后端平台 API、数据库 SQL、core 配置
- 更新前端多个视图组件及 API 模块
- 重构 frontend/dist 构建产物（新 hash）
- 更新多项文档
