检查点：#66 / R3-02 积压断开已推送

完成

• 分支 feat/fix-r3-66-disconnect HEAD a14ca0d，已推送 origin，未合 main。
• 带断开下行：本帧 OnPacketSent（packet id / 载荷）等待，去掉连接级 sentPub。
• Shutdown：ctx 未取消时先 waitConnsQuiet（downCh + wirePending），再 DisconnectClient 发 0x8B，waitConnsGone；已取消则发完即 Close。
• DEVIATIONS 追加「复审修复 R3-02」。Gitea #66 已评论。

验证

• go test ./internal/broker/ 通过
• go test ./cmd/nixmsg/ 通过

给下个会话

• 可 rebase origin/main 后由总控合入；不要合 feat/fix-3-downlink-deadlock。
