ping_host 仅 except OSError，但握手期 _recv_exact_sock 抛的 TdxConnectionError 继承自 TdxError(Exception) 而非 OSError，逃出捕获后经 ping_all 的 fut.result() 重新抛出，导致非交易时间服务器 accept 后立即 FIN 时整个 easy-tdx ping 崩溃。 - ping_host: except (OSError, TdxConnectionError)，对齐 docstring 返回 None - ping_all: fut.result() 加 try/except 防御层，单 host 失败只跳过不崩 - 新增 2 例回归测试
