杭州明婳科技 6595e94677 fix: 多模型评审终审收口 — P0安全 + 主线A并发治理 + 文档对齐
经 deepseek/GLM/Claude 三轮对抗性评审 + 交叉核验 + 终审(见
last_report.md、cross_review_assessment.md),逐条回读源码核实并修复。
go build / vet / test -race ./... 全绿。

安全(P0):
- JWT alg confusion:WithValidMethods 固定 HMAC + keyfunc 方法断言
- JWT 空密钥 / 不支持算法 fail-closed(ErrEmptySecret / ErrUnsupportedAlgorithm)
- 上传大小实测封顶(enforceUploadSize),不信任客户端 file.Size
- HTTP headers/cookies map 竞态(写锁+快照)+ SSRF 防护(opt-in dialer.Control)

并发/资源(主线A 闭合):
- 包级可变全局一律 atomic.Pointer:DefaultRedis / DefaultStorage /
  DefaultManager / Validator / DefaultCache 等,消除裸指针数据竞争
- trace.Close 去 sync.Once(防 exporter 泄漏);app OnReady 失败走 Shutdown
- ws.Hub.Stop stopOnce 防 double-close;cron 接入 App 生命周期(WithCron)
- ratelimit failClosed atomic.Bool;Recover Written() 守卫
- cron checkAndRun 锁内收集锁外 spawn(wg.Add 在锁内防 Stop 竞态)

终审剩余项收口(H-A~M-H + L 系列):
- 副本连接池 MaxOpenConns/2 截断修复(replicaMaxOpenConns)
- JWT 黑名单 1s 超时 + 显式错误;ratelimit GetRedis 取一次复用
- GetPage 深分页上限;HashFile 流式;ReadFile 去 TOCTOU
- config Clone() 深拷贝;cache 锁操作返 ErrRedisNotReady
- compress 解压残留清理;正则预编译;EqualsIgnoreCase→EqualFold
- 删 redisLimiters 死代码;CLI 输入校验 + 回滚

文档:
- README/GUIDE/CHANGELOG 对齐当前 API(含破坏性变更迁移说明)
- docs/README 索引修正;config 注释修正(RS256 已不支持)

破坏性变更详见 CHANGELOG.md [Unreleased]。项目处于研发初期、无下游用户。
