/**
 * 批 3 排队 —— **HTTP 层**(27-P3C §六.3)
 *
 * 与另外两份的分工:
 *   · `task-scheduler.test.js`        单个原语的形状(准入守卫、CAS 的 WHERE、唯一索引的取值域)
 *   · `task-queue-acceptance.test.js` 服务层端到端(推 `sse.transitionRun` 这个漏斗,看队伍动没动)
 *   · **本文件**                       真的打 HTTP,验「端点接上了没有」
 *
 * 为什么非要有这一份:批 3 的前一轮把 `launchTaskRun` 改名成 `enqueueTaskRun`,**两个调用点
 * 一个都没改** —— `POST /:cid/tasks` 与 `goals/:goalId/dispatch` 一打就是
 * `ReferenceError: launchTaskRun is not defined`,而队列的服务层测试全绿:它们一律直接调
 * services,从不经过路由。同时 `promoteQueuedTask` / `cancelQueuedRun` / `queueReply` /
 * `queuePositions` 四个函数**零调用方**躺在文件里,注释写着「本函数是人工出队那条路」,
 * 而那条路根本没有入口。这正是 §九.4quater 点名的惯犯模式:「实现在、零调用方」。
 *
 * 所以这份的每一条用例都从 URL 打进去。**能被服务层测试覆盖的语义这里不重复验**,
 * 只验路由这一层独有的东西:端点存在、状态码、响应体形状、以及「谁在按钮上点得动」。
 *
 * ⚠️ 先设 env 再 require(graph-engine / graph-run-sse 在模块加载时快照 GRAPH_RUNS_DIR,
 * 先 require 再设会往仓库 data/companies/ 里写,而且不报错)。
