// 三组测试,按 groupOrder 依次跑:
//   unit   —— 纯内存、无 PG,文件并行;
//   pg     —— 真实 PG、假引擎(每文件独立 schema),文件并行;
//   serial —— 起真实引擎 / worker / 后台循环 / 子进程的集成与 e2e,文件级串行。并发跑时 worker、轮询、迁移
//             互相抢 CPU 与连接,会把"入库→状态推进"这类时序拉长到超时,串行让每个文件拿到稳定的时序预算。
// 新测试缺省进 pg;起真实 worker / 引擎 / 子进程的加进 SERIAL;确认不碰 PG 的加进 UNIT。
// 并行文件数受开发库连接数约束(max_connections 100,每个 harness 连接池 5–10):MAX_WORKERS 别随手调大。
