检查点：fix issue #5 metrics 打点（已推分支，未合 main）

范围

• 工作树 e:\\code\\NixMsg-wt\\fix5
• 分支 feat/fix-5-metrics → origin/feat/fix-5-metrics
• 提交 b4789fc（基线 479a08e）
• issue #5；未合并 main；未关闭 issue

完成

• nixmsg_connections{ws|tcp}：broker OnSessionEstablished/OnDisconnect 末尾 Inc/Dec
• endpoints/deliveries_pending/messages_scheduled + 写队列/哈希排队：messageLoops 每秒采样真实值
• dispatch_to_push/ack 直方图：PushPending 成功推送、Ack 成功确认时 Observe
• write_batch_commit：store.Queue.OnBatchCommit
• errors_total：uplink replyErr
• DEVIATIONS 追加 ### fix-issue-5
• 未改 group emit / 管理锁定 / 注册 IP / fatal；避开 PublishDown 与 dissolve 回执大段

验证

• go test ./internal/metrics/ ./internal/broker/ ./internal/app/message/ ./internal/store/ ./cmd/nixmsg/ ./internal/httpx/ 通过
• 未跑全仓 task check

下一步

• 总控审阅后 ff-only 合 main；本线勿合 main
• 与 feat/fix-3-downlink-deadlock、feat/fix-6-dissolve-receipt 合并时注意 hooks 末尾与 ack 小 diff
