test(http2,http3,proxy): 改进测试覆盖边界情况
- http2/adapter_test.go: 替换 pool reuse 测试，新增 header 转换边界测试 - 空头测试、特殊字符、多值头、长头名称 - http3/server_test.go: 替换 stats struct 测试，新增 Alt-Svc 头边界测试 - 端口边界值、禁用服务器、nil 配置 - http3/mock_test.go: 添加 QUIC listener mock 用于测试 - proxy/proxy_test.go: 添加 UpstreamTiming 边界测试 - 零值测试、部分标记测试 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
