Unity console keeps logging warning message: "Error communicating with Python server: The operation is not allowed on non-connected sockets."

[lingllting]

The Unity MCP Editor Window has a periodic check (every 2 seconds) that tries to verify the Python server connection:

if (Time.realtimeSinceStartup - lastCheckTime >= CONNECTION_CHECK_INTERVAL) // CONNECTION_CHECK_INTERVAL = 2f
{
    CheckPythonServerConnection();
    lastCheckTime = Time.realtimeSinceStartup;
}

This check tries to:
Connect to localhost:6400
Send a "ping" message
Wait for a "pong" response

The issue is that this check is using a different connection mechanism than the actual MCP commands. When you create objects or perform other actions, those go through the established MCP connection, but this status check creates a new TCP connection each time.
The error messages come from these periodic checks failing to establish new connections, even though the main MCP connection (used for actual commands) is working fine.

Drastically extended the timeout (now 24 hours) and the buffer size. Should be fixed now since PR #68
