Describe the feature request

Summary
Currently, active XTCP P2P sessions are torn down whenever the frpc–frps control connection becomes temporarily unavailable. This causes unnecessary interruption to ongoing traffic, even though the P2P data channel itself remains healthy.

Problem
In environments with unstable networks, short disruptions in the frpc–frps connection can occur frequently. When this happens:

The control channel disconnect triggers the teardown of the associated XTCP tunnel.

The client and visitor must re-establish the P2P session even though their data path was still functional.

This leads to degraded user experience and additional overhead for reconnecting.
