+/**
+ * 三端验证工作流编排器（Task 97）。
+ *
+ * 把 Java 全量测试、Python unittest、Vue 类型检查与构建四个验证步骤
+ * 收敛为可注入执行器的确定性流程：步骤按序执行，产出逐项结果。
+ *
+ * 语义：
+ * - 每个步骤的 run(stepId) 返回 { ok, output }；ok=false 时计入 failed；
+ * - stopOnFailure（默认 true）下失败即停止，剩余步骤计入 skipped；
+ * - maxSteps 限制可执行步骤数量（超出部分计入 skipped），执行有界；
+ * - 步骤执行器抛错：整次 runAll 抛错，不产生部分结果记录（调用方可
+ *   捕获后恢复重跑同一 runner）；
+ * - 校验失败 fail-fast：steps 非数组、step id 为空、run 非函数、maxSteps
+ *   非正数、run 返回结果缺 output 均抛错。
