Rye generates empty `rye_errors.log` file even if it is not needed

[stefanb]

An empty file rye_errors.log is created in current directory even if there are no errors produced, eg after running a simple rye --help or rye --version.

It seems it is created during logger initialisation:

rye/runner/runner.go

Lines 76 to 89 in 1370040

	// initErrorLogging initializes the error logging system
	func initErrorLogging() {
	// Try to open error log file
	var err error
	errorLogFile, err = os.OpenFile("rye_errors.log", os.O_APPEND|os.O_CREATE|os.O_WRONLY, 0644)
	if err != nil {
	fmt.Fprintf(os.Stderr, "Warning: Could not open error log file: %v\n", err)
	errorLogger = log.New(os.Stderr, "ERROR: ", log.Ldate|log.Ltime|log.Lshortfile)
	} else {
	// Create multi-writer to log to both stderr and file
	multiWriter := io.MultiWriter(os.Stderr, errorLogFile)
	errorLogger = log.New(multiWriter, "ERROR: ", log.Ldate|log.Ltime|log.Lshortfile)
	}
	}

Hm .. yes ... you are correct that that is not the best behaviour. I will change it so it's only created if there is something to log.
