Support createMain(command) return value from run method

[peterroe]

Describe the feature

import { createMain, defineCommand } from 'citty'

const command = defineCommand({
	//...
	async run() {
		return Promise.resolve("hello")
	}
})

const apiCommand = createMain(_rDefault(command))
 
const value = await apiCommand({
	rawArgs: []
})
console.log(value) //=> "hello"

Additional information

• Would you be willing to help implement this feature?

Do you mean line 10 looks like below?

const apiCommand = createMain(_rDefault(command))

By the way, this issue would be able to be handled as a part of #94, wouldn't it?
So, let me close this issue and watch #94.

Please reopen this issue if this issue is about different topics.

Let's keep both open until landing an API that supports both usecases :)

(@nozomuikuta kindly please ping maintainer instead of doing actions like closing issues, i could simply forgot about this issue)

I see, thank you for the gentle notice 🙏

Returning a value from the run method will be very useful for API call scenarios. If it proves feasible, I will initiate a PR to implement that. :)
