/**
 * cluster/index.ts — Cluster 模块公共导出入口
 *
 * 集中导出 cluster 子模块的公共 API，
 * 外部通过 import { ... } from './cluster/index.js' 访问。
 *
 * 导出内容：
 *   - ClusterMaster:    Master 进程主类
 *   - workerMain:       Worker 进程入口函数
 *   - resolveWorkerCount: Worker 数量计算
 *   - PID 文件操作:     writePidFile / readPidFile / removePidFile / isProcessAlive
 *   - IPC 类型:         消息类型定义 + WorkerMeta + WorkerMetrics
 *   - Cluster 检测:     checkClusterCompatibility
 *   - 配置类型/默认值:  ClusterMasterConfig / DEFAULT_CLUSTER_CONFIG
 *
 * @module lib/cluster
 * @see 12-cluster.md（多进程 Cluster 设计方案总览）
