Support `setup` to return data

Describe the feature

export default defineCommand({
    meta: {
        name: 'test',
        description: 'Test command',
    },
    async setup(context) {
        const data = someComputed(context)
		return { data }
    },
    async run({ args }, { data }) {
		console.log(data)
	}
})

Reason

The return value of setup could be useful, in addition to some initialization behavior, it could potentially produce different values depending on the context, which could be used in setup and passed to all subcommands in the run method arguments!

Of course, I may not have thought this through completely, does anyone else have a better suggestion?

Additional information

• Would you be willing to help implement this feature?

No file or test is named. Start by tracing the defineCommand lifecycle from setup into run and inspect how arguments are passed to subcommands. Done should mean setup can return context-dependent data and run receives that data, with tests covering the new behavior.
