M5(2/3): process 用例与流转 —— 流程引擎的确定性调度

- routing domain:选边(XOR 恰取一条 + 默认分支兜底;AND 全走)、边映射装配(四类来源 +
  S-FEEL 转换)、AND 汇合回齐(容忍分支不阻汇合)、审批点驳回走向声明式
- process-service:起单 → 调度节点 → 负责人四策略解析(结果与依据留痕)→
  活动起单 / 审批点卡工位 / 终点收束按来源回执;任务终态到达继续流转或走失败走向四选一;
  审批驳回按声明回指定节点重开新实例;状态每次变动后重算聚合投影
- adapter:流程包(id × version)、工作流实例、节点实例三表持久 —— 崩溃后可续跑

ADR 待补项登记为 debt M5-1:§6.1 的 Mastra workflow 编译器作为可替换 adapter 后补,
当前由自持确定性状态机承担,语义等价、usecase 不动

325 个测试通过,门禁五道全绿
