Warren d585a5ee96 Phase 16.5: 100MB diagnosis - no CHANNEL_DATA packets received ...

关键发现：
- iteration 0多次启动（poll loop多次调用）
- CHANNEL_DATA packet: 0次 ⚠️⚠️⚠️⚠️⚠️
- child process正常退出
- rsync client显示传输成功

问题诊断：
- SSH server没有接收rsync数据
- 可能使用SFTP subsystem（不是exec）
- 需要检查SFTP handler

下一步：检查SFTP subsystem处理逻辑
