/**
 * 龙虾引擎全行业验证 - 第一批基础验证
 *
 * 通过 HTTP 调用 /api/lobster/admin/validation/** 完成基础验证：
 *   第1步：基础信息获取（health / industries / node-capabilities）
 *   第2步：语义意图识别（全行业 × 3条典型消息）
 *   第3步：敏感词全量验证（list + 逐词 check）
 *   第4步：Token 统计（daily / model）
 *   第5步：进化指标（evolution / learning）
 *
 * 技术要求：
 *   - Java 11+ HttpClient（java.net.http.HttpClient）
 *   - JSON 使用字符串拼接 + 正则解析，不依赖外部库
 *   - 默认请求超时 30 秒；语义/敏感词检测为 LLM/缓存预热场景，超时放宽至 150s/60s
 *
 * 编译运行：
 *   javac -encoding UTF-8 FullIndustryValidation.java
 *   java -cp . FullIndustryValidation
 *
 * 输出：reports/full-industry-validation-batch1.json
