BREAKING CHANGE: command names are not derived from modules passed to `command`.
BREAKING CHANGE: Supported Node.js versions are now ^20.19.0 || ^22.12.0 || >=23.
BREAKING CHANGE: singleton usage of yargs yargs.foo, yargs().argv, has been removed.

-### ESM
-
-As of `v16`,`yargs` supports ESM imports:
-
-```js
-import yargs from 'yargs'
-import { hideBin } from 'yargs/helpers'
-
-yargs(hideBin(process.argv))
-  .command('curl <url>', 'fetch the contents of the URL', () => {}, (argv) => {
-    console.info(argv)
-  })
-  .demandCommand(1)
-  .parse()
