fix: make require("cliui") work as expected for CJS

[bcoe]

@shadowspawn this uses the suggestion you gave in yargs adding:

export {ui as 'module.exports'};

Which seemed to make things work pretty well for both CJS and ESM:

const ui = require('cliui')()
const {Chalk} = require('chalk')
const chalk = new Chalk();
ui.div('Usage: $0 [command] [options]')

ui.div({
  text: 'Options:',
  padding: [2, 0, 1, 0]
})

import cliui from "cliui";
import chalk from "chalk";
// Deno: import cliui from "https://deno.land/x/cliui/deno.ts";

const ui = cliui({})

Thoughts? Do you think this hack (export {ui as 'module.exports'};) is reasonable, or is it going to bite us one day.

The documentation is a bit unclear about whether it should be needed, but when I was looking at yargs it did seem to be needed in practice. It might be a while before I can do some research.

I did some simple sanity checking. bun and deno don't currently support the (recent) variant syntax, it is a node special. But didn't cause any problems as such.

// def.cjs

const def = require('./lib.mjs');
console.log({def});

// lib.mjs 

const defaultValue = "DEFAULT";
export default defaultValue

export {defaultValue as 'module.exports'};

$  node def.cjs          
{ def: 'DEFAULT' }

$ deno run --allow-read def.cjs
{
  def: [Module: null prototype] {
    __esModule: true,
    default: "DEFAULT",
    "module.exports": "DEFAULT",
  }
}

$ bun run def.cjs       
{
  def: Module {
    default: "DEFAULT",
    "module.exports": "DEFAULT",
  },
}

There is an issue open again Deno noting the new require(esm): denoland/deno#26649

No problems with running an esm entry point.

// modern.mjs

import def from './lib.mjs';
console.log({def});

$ node modern.mjs 
{ def: 'DEFAULT' }
$ deno run --allow-read modern.mjs
{ def: "DEFAULT" }
$ bun run --allow-read modern.mjs
{
  def: "DEFAULT",
}
