chore: fresh-clone 可直接运行审查与修复

确保 git clone 后零配置(除 LLM key)即可跑通后端链路。

- go.work: 移出 sundynix-desktop(Wails，//go:embed frontend/dist 需先 npm build，
  且 main 为桩)，避免污染后端工作区构建；保留后端 4 模块
- mcp-py pyproject: 注释未 import 的 mcp/docker 重依赖(对应功能仍为桩)，
  fresh pip install 只装实际用到的 nats-py + docx/openpyxl/pypdf，更快更稳
- README: 完整环境改为 fresh-clone 零配置运行指引(infra→4后端→2前端→控制台配模型)
- 审查结论: 无硬编码绝对路径; 各服务 env 默认全对齐 docker-compose; go.sum/
  package-lock 齐全; /tmp clone 实测: 4 后端模块 go build ✓、admin npm ci+build ✓、
  mcp-py 全新 venv 安装+导入 ✓; e2e PASS
