fix: set SilenceUsage/SilenceErrors and print errors to stderr

[pageton]

Summary

The root command is missing two critical Cobra settings, and errors are printed to stdout instead of stderr.

1. Missing SilenceUsage and SilenceErrors

main.go:13-16:

rootCmd := &cobra.Command{
    Use:   "gorm",
    Short: "GORM CLI Tool",
}

Without SilenceUsage: true, Cobra prints the full usage/help text on every RunE error. Without SilenceErrors: true, Cobra also prints the error itself, so the manual fmt.Println(err) in main causes the error to appear twice.

2. Error printed to stdout

main.go:22:

fmt.Println(err)

This writes to stdout. Errors must go to stderr so they don't corrupt piped output when the CLI is used in pipelines.

Fix

rootCmd := &cobra.Command{
    Use:           "gorm",
    Short:         "GORM CLI Tool",
    SilenceUsage:  true,
    SilenceErrors: true,
}

// In main():
if err := rootCmd.Execute(); err != nil {
    fmt.Fprintln(os.Stderr, err)
    os.Exit(1)
}
