Phase 6: 部署文档 + 启动脚本 + 配置样例

- README.md (英文): 项目概览 + 11 Tool 表格 + 12 env 变量全表
  + 6 admin 端点 + 安全模型 (3 道防线 + 4 项额外保证) + dev 命令
- .env.example: 12 env 变量 + 默认值 + 必填标注
- scripts/dev.sh: 一键 build + 后台启动 (nohup + PID 文件) + healthz 验证
- scripts/seed.sh: admin POST 一个示例 cluster (从 .env 读 admin token)
- ARCHITECTURE.md (中文): 包依赖图 + 数据流 + 11 Tool 分类 + 关键设计决策
- docs/runbook.md (中文): 部署 + 升级 + 故障排查 (401/404/422 等)
- docs/systemd/spark-mcp-go.service: systemd unit 模板

README 安全模型小修正: 第 3 道防线从"spark_submit flag 白名单"
(实际不存在) 改为 "upload_file 路径白名单", 加 Additional guarantees
小节列 slice form / json:"-" / 跨主机 redirect / per-tool log 权限。
