/**
 * OpenClaw VOC Skills 一键部署脚本
 * 
 * 功能：将 skills 文件夹中的所有技能部署到 OpenClaw 的 skills 目录
 * 兼容：Windows / macOS / Linux
 * 依赖：仅需 Node.js（OpenClaw 已自带）
 * 
 * 使用方法：
 *   node install.js                    # 部署所有技能
 *   node install.js --list             # 仅列出技能，不部署
 *   node install.js --only a,b,c       # 仅部署指定技能
 *   node install.js --skip a,b,c       # 跳过指定技能
 *   node install.js --target /path     # 指定目标目录（默认 ~/.openclaw/skills）
 *   node install.js --clean            # 部署前清空目标目录
 *   node install.js --dry-run          # 预览模式，不实际写入
