优化自适应扫描系统 & 修复 POC 调度问题

自适应扫描优化:
- target/ceiling 分离，自适应池可向上探索而非锁死在 target
- assessHealth 阈值按网络环境区分（LAN 收紧 / Internet 放宽）
- RTT 漂移时动态压低 target，配合 AIMD 双重降速
- 去掉 semaphore 双层流控，由 ants pool 统一反压
- 探测端口从 3 个扩充到 8 个，减少 RTT 采样偏差
- computeRetries 按环境调整目标概率和上限

Bug 修复:
- AdaptivePool.Wait() 加 10 分钟超时，防止 goroutine 卡死时永久挂起
- CEL 环境初始化失败后允许重试（sync.Once → sync.Mutex + 标志位）
- CAS 自旋加 runtime.Gosched() 退避，减少高并发下 CPU 空转
- -full 模式下 web 插件跳过 IsMarkedWebService 检查 #588
- 不确定服务补做 HTTP 回退探测，覆盖自定义框架漏网场景
- POC sets 纯字面量值跳过 CEL 编译，消除大量误报错误日志
