aiko-chan-ai/discord.js-selfbot-v13 ? reverse-engineered prompt

Build me a Node.js library like discord.js, but for user accounts on Discord API v9, with the same kind of event based client, message handling, status and activity updates, guild member fetching, join and leave actions, emojis, slash commands, buttons, menus, modals, captcha and TOTP handling, and voice and video support.

I want it to feel like a polished package people can install and use right away, with a simple client login flow, clear docs, TypeScript typings, and a few example scripts that show the main features in action. Make the code structure clean and easy to extend, and base it on the older discord.js v13 style with some newer behavior backported where it makes sense.

If you need to look up current Discord or Node docs online while building it, go ahead.
