Description

客户端 naive outbound，通过 SFA 测试延迟以后，服务端 naive inbound 在 QUIC 模式下，客户端取消 CONNECT 请求时，出现了预期之外的 ERROR 日志：

ERROR connection: connection upload closed: H3_REQUEST_CANCELLED

可能是 sing/common/baderror/baderror.go 的 WrapH2() 函数缺少对 HTTP/3 特有取消错误的匹配。现有模式 "; CANCEL" 匹配的是 HTTP/2 的 stream error: stream ID x; CANCEL 格式，而 quic-go/http3 返回的错误字符串是 H3_REQUEST_CANCELLED（HTTP/3 错误码 0x0108），不包含 "; CANCEL" 子串。

错误未被转换为 net.ErrClosed，导致 route/conn.go 中 IsClosedOrCanceled() 无法识别，走了 ERROR 分支而非 TRACE。

这个报错，只有在naive outbound启用quic时，才会出现。使用默认的HTTP/2，不会出现这个问题

Reproduction

服务端和客户端均使用sing-box，分别配置naive入站和出站，naive出站启用quic，点击SFA延迟测试按钮，可以100%复现。

Integrity requirements

• I confirm that I have read the documentation, understand the meaning of all the configuration items I wrote, and did not pile up seemingly useful options or default values.
• I confirm that I have provided the server and client configuration files and process that can be reproduced locally, instead of a complicated client configuration file that has been stripped of sensitive data.
• I confirm that I have provided the simplest configuration that can be used to reproduce the error I reported, instead of depending on remote servers, TUN, graphical interface clients, or other closed-source software.
• I confirm that I have provided the complete configuration files and logs, rather than just providing parts I think are useful out of confidence in my own intelligence.
