fix: app can't be restarted successfully when the application has close-blocking interactive behavior

Description

fix: app can't be restarted successfully when the application has interactive behavior that prevents closing (such as a confirmation dialog box).

Additional context

The code that may trigger the bug:

mainWindow.on('close', (e) => {
  dialog.showMessageBox({
        title: 'App Shutdown Notice',
        message: 'Are you sure to shutdown the application?',
        type: 'info',
        buttons: ['Ignore',  'Exit'],
      })
        .then((result) => {
          if (result.response === 1)
            app.quit()
        })
})

The solution:

const watchHook = (): void => {
  logger.info(colors.green(`\nrebuild the electron main process successfully`))

  if (ps) {
    logger.info(colors.cyan(`\n  waiting for electron to exit...`))

    ps.removeAllListeners()
    ps.on('exit', () => {
      ps = startElectron(inlineConfig.root)
      logger.info(colors.green(`\nrestart electron app...`))
    })
    ps.kill()
  }
}

In this code, I added an exit event listener, which starts a new Electron process after the old Electron process exits. This ensures that the new Electron process starts only after the old Electron process has completely exited.
