+     * 审计事件处理线程池 - 使用虚拟线程（Java 21+）
+     * 
+     * ⚠️ 为什么使用虚拟线程？
+     * 1. 审计事件处理是**I/O密集型**任务（写日志、写数据库）
+     * 2. 虚拟线程在I/O阻塞时不占用OS线程，资源消耗极低
+     * 3. 审计事件量可能很大，虚拟线程支持高并发处理
+     * 4. 独立线程池避免与业务线程池竞争资源
+     * 
+     * 💡 场景：
+     * - 异步记录用户操作审计日志
+     * - 写入审计数据库
+     * - 发送审计事件到消息队列
+     * 
+     * 🎯 解决问题：
+     * - 修复 "More than one TaskExecutor bean found" 警告
+     * - 确保审计事件处理不受其他业务线程池影响
