when setting default command to gcli app, ./appcli can't run with default command

[justz0]

System (please complete the following information):

• OS: windows 10
• GO Version: 1.21.6
• Pkg Version: v3.2.3

Describe the bug

I set a ‘run’ command for the app through ‘app.SetDefaultCommand’, and want the app to execute the ‘run’ command by default (./app). But after compiling, I run ‘./app’ and get an error ‘ERROR: unknown input command "run"’

To Reproduce

package main

import (
	"fmt"
	"github.com/gookit/gcli/v3"
	"log"
)

var run = &gcli.Command{
	Name:    "run",
	Desc:    "run app client",
	Func: func(c *gcli.Command, args []string) error {
		//server.Run()
		fmt.Println("test default command")
		return nil
	},
	//Hidden: true,
}

func Run() {
	app := gcli.NewApp()
	app.Version = "1.0.0"
	app.Name = "Test Client"
	app.Desc = ""
	app.Add(run)
	app.SetDefaultCommand(run.Name)
	app.Run(nil)
}

func main() {
	Run()
}

Expected behavior

I expected to happen: execute "./app" command, then the app will execute 'run' command,just like execute "./app run"

func (app *App) prepareRun() (code int, name string) {
	// find command name.
	name = app.findCommandName()
	if name == HelpCommand {
		if len(app.args) == 0 { // like 'help'
			app.showApplicationHelp()
		} else {
			// like 'help COMMAND'
			code = app.showCommandHelp(app.args)
		}
		return
	}

	// not input and not set defaultCommand
	if name == "" {
		if app.Func != nil {
			code = app.doRunFunc(app.args)
		} else {
			app.showApplicationHelp()
		}
		return
	}
    
	// name is not empty, but is not command.
	if app.inputName == "" {
		Logf(VerbDebug, "input the command is not an registered: %s", name)
		hookData := map[string]any{"name": name, "args": app.args}

		// fire events
		if stop := app.Fire(events.OnAppCmdNotFound, hookData); stop {
			return
		}
		if stop := app.Fire(events.OnCmdNotFound, hookData); stop {
			return
		}

		app.showCommandTips(name)
		return
	}

	// is valid command name.
	app.commandName = name
	return GOON, name
}

I debug to this code , app.inputName is empty ，Caused the default command to fail
