test: complete bounded HTTP2 TLS soak and flow control checks

CHANGELOG.md

 - HTTP/2 实验 Runner 增加标准 1 MiB 头部上限、默认 8 MiB 请求体上限、128 路同连接多路复用、2 MiB 慢读取流控验收、协议错误、RST_STREAM 和 GOAWAY 帧计数；已声明超限请求在进入业务 handler 前返回 413。
 - 新增可配置时长的 HTTP/2 TLS soak：默认 3 秒，Linux 验收可通过 `GO_OMNI_HTTP2_SOAK_DURATION=30m` 覆盖，混合验证 128 路 stream、慢 handler、请求体、Keep-Alive 和退出回收。
 - HTTP/2 soak 每 15 秒输出请求/失败数、Go 堆、Linux RSS、goroutine、FD 和协议统计；校验响应协议、内容和独立请求 ID，不再忽略压测期限附近已发出请求的失败。
+- 补充 HTTP/2 慢响应流窗口为零时的隔离与恢复验收：同连接 204、另一连接带 body 响应、WINDOW_UPDATE 恢复发送及 RST_STREAM 释放请求槽位；补充 TLS 握手未完成时的连接上限拒绝、握手超时回收和正常请求恢复。
 - 新增 `scripts/verifyHTTP2.py`，固定在 Go 1.25 Linux 容器中运行 HTTP/2 TLS 长测；默认使用普通模式，`--race` 默认运行 60 秒。容器默认限制为 2 核、2 GiB 内存、256 个进程/线程，带总时限、中断清理和日志大小限制。
+- 完成 Linux amd64 单 TLS 连接、128 个 worker 的 30 分钟 HTTP/2 长测：58,102,476 次请求，0 失败与协议错误，采样 RSS 峰值约 22.6 MiB（包含客户端和服务端），退出后连接/请求/FD 回收；保留原始日志和 120 份采样。多连接、持续慢客户端与 HTTP/2 回源联调仍是后续门槛。
 - native TLS 明确限制 ALPN 为 `http/1.1`：缺省自动宣告该协议，误配置 `h2` 等未实现协议时在启动阶段报错。
 - native `Server.Stats()` 新增连接和请求过载拒绝计数；新增可信代理配置，访问日志只在 socket 对端属于配置网段时解析 `X-Forwarded-For`。
 - 新增 transport-neutral `metrics` 包，支持请求数、错误数、in-flight、累计耗时和状态分布，并可直接注册 `/metrics` 接口。

 HTTP/2 仍是显式 opt-in 实验适配器，不会改变 native 的 HTTP/1.1 默认路径。Linux TLS 长测使用 `python3 scripts/verifyHTTP2.py --duration 30m`，默认使用普通 Go 运行模式；`--race` 默认改为 60 秒，用于并发检查，其额外内存开销不能当成生产运行基线。
 
-该脚本默认把测试容器限制为 2 核、2 GiB 内存（禁用 swap）、256 个进程/线程，整个命令最多运行 40 分钟，中断和超时会清理本次容器。这些限制可用 `--cpus`、`--memory-mb`、`--pids-limit`、`--wall-timeout` 调整；共享服务器应先用 `--duration 60s` 短测，再逐步延长。每 15 秒输出的堆、RSS 和 FD 统计包含同一进程内的客户端与服务端；当前验证范围见 [Linux HTTP/2 短测记录](performance/http2SmokeLinux.json)。

 - native TLS 已明确只宣告 HTTP/1.1 ALPN；HTTP/2 暂由边缘代理终止或使用 `transport/nethttp`，已整理独立协议设计、流控和压测门槛，见 [native HTTP/2 进入条件](transport/native/HTTP2.md)，完成后再接入 native。
 - 已加入独立 `transport/http2` 实验 Runner，验证 h2c/TLS h2、连接上限、全局请求并发拒绝和恢复，以及 GOAWAY 排空、RST_STREAM 单流取消和服务关闭超时；它使用 `x/net/http2` 作为临时帧/流控实现，尚未达到 native 生产协议的流控和长测门槛。
 - HTTP/2 实验已补齐头部/请求体上限、128 路同连接多路复用、慢读取流控、协议错误、RST_STREAM 与 GOAWAY 统计，并提供 `scripts/verifyHTTP2.py --duration 30m` 的 Linux TLS 长测入口；长测默认不启用 race，短时并发检查使用 `--race`（默认 60 秒）。测试容器默认限制为 2 核、2 GiB 内存、256 个进程/线程，并设总时限和退出清理；代理联调和长测结果仍是进入 native 前的门槛。
