Main `--help` does not show command description:

[rubythulhu]

When I have a root command with sub-commands, as in:

import { CliCommand } from "cilly";
import { pkgUp as getPackageJson } from "pkg-up";
import { readFile } from "node:fs/promises";
import { URL } from "node:url";

const cmd1 = new CliCommand("hello")
  .withDescription("say hello")
  .withHandler(() => console.log("hey babe"));

const cmd2 = new CliCommand("goodbye")
  .withDescription("say goodbye")
  .withHandler(() => console.log("ttyl hun"));

const root = new CliCommand("mytool")
  .withVersion('1.2.3')
  .withDescription("My tool description")
  .withSubCommands(cmd1, cmd2)
  .withHandler(() => root.help());

await root.process(process.argv);

Expected Output:

Usage: mytool [options]

My tool description

Options:
  -h, --help         Display help for command
  -v, --version      Display the version

Commands:
  hello [options]    say hello
  goodbye [options]  say goodbye

Actual Output:

Usage: mytool [options]

My tool description

Options:
  -h, --help        Display help for command
  -v, --version     Display the version

Commands:
  hello [options]
  goodbye [options]

Why are descriptions of sub-commands not included in help output?

Is there any way I can fix this in my local project without re-implementing everything in the basic help output, but also providing this extra output? I just want the root command's --help to actually show what each subcommand does?

I do not wish to force the end user to run each and every [root-cmd] [sub-command] --help individually, collate this information into their own "how do i even use this tool" mycommand-cheat-sheet.txt, just to find out what each sub-command even does.

At present, it seems my only option is to completely override the help handler for the root command, individually re-implement all of the sections other than Commands:, then finally re-implement the Commands: section to provide this information. This seems like a hostile API interface though, so i am assuming i'm missing something?
