[Bug] Server fails to close properly when calling close() method

[AnyOpenGL]

When attempting to create an instance using the following code:

object Example {
  val server by lazy {
    configServer()
  }
}

Everything works normally, including the MCP server running properly. However, when I try to call close() on the server:

1. The server doesn't shut down as expected
2. The ports are not being released

Expected Behavior:

1. The server should terminate properly when close() is called
2. All occupied ports should be released

Request:
Could someone help investigate why the server isn't closing properly and how to fix this issue?
