nb-workflow

@notnotype/nb-workflow 是会记账的脚本式 Workflow 引擎。Workflow 是普通 async 函数；Activity 的输入、输出和身份写入 journal，进程恢复后不会重复已完成步骤。

import {MemoryActivityExecutor, WorkflowRunner} from "@notnotype/nb-workflow";

const activities = new MemoryActivityExecutor();
activities.registerAction("math.double@1", ({value}: {value: number}) => ({value: value * 2}));
const runner = new WorkflowRunner({}, {}, {activities});

Activity 引用必须显式带版本。内存实现只用于测试和 demo；Agent、Session、Workspace 通过 SessionPort、AgentPort、WorkspacePort 注入。进一步阅读：Activity 与重放、等待与恢复、API。
