fix(desktop): swallow EPIPE on std streams (Windows GUI launch crash) 

On Windows Squirrel/GUI launches there is no attached console, so
process.stdout/stderr are dead pipes. The daemon-output console.log/error
calls failed with EPIPE and, lacking an error listener, crashed the main
process with 'A JavaScript error occurred in the main process'. Add an
error listener that ignores broken-pipe writes.
