feat(commands): Add base Application Commands integration

[TomerRon]

This PR adds Application Commands to cordless, allowing bots to register commands and react to them. For now, only basic interactions are possible. Future PRs will add additional features like accepting options, responding with interactive buttons, and more.

Basic Commands usage

const ping: BotCommand = {
  name: "ping",
  description: "Replies to your ping.",
  handler: ({ interaction }) =>
    interaction.reply({
      content: "Pong!",
    }),
};

init({
  applicationId: process.env.APPLICATION_ID,
  commands: [ping],
  functions: [],
  token: process.env.BOT_TOKEN || "",
});

Note: your bot's application ID can be found in the Discord developer portal. It's only required if you are using commands.

---

Breaking changes

• The bot token must now be passed into the initialization method (even if you are not using commands)
• The client now logs in automatically, so you should not call .login(token) anymore

Previous:

init({ functions: [...] }).login(process.env.BOT_TOKEN)

New:

init({
  functions: [...],
  token: process.env.BOT_TOKEN || "",
});
