[retrouser955]

This pull requests adds the ability to configure application command context which allows the creation of user-installable commands.

I have not tested this feature yet so the pull request will be a draft for now.

Hey, I just have a couple of questions. Would you add the context of the application command usage CommandInteraction or CommandInteractionData?

Right now, I have it set to the former and I was just checking if changes are needed.

Edit: Question answered via Discord

Please lint.

Missing ApplicationCommand typings. Also when you lint, please use the script provided in package.json

discord/discord-api-docs#6958 may need to be looked at in relation to this as well

Oh sorry, I didn't see that USE_EXTERNAL_APPs has been implemented already.

Still missing interaction metadata implementation (deprecating message.interaction). Lint typings

Pull Request Overview

This PR adds support for Discord's user-installable application commands, enabling bots to be installed by users directly and used across different contexts (guilds, bot DMs, and private interactions).

• Adds context properties to track where interactions originate (guild, bot DM, or private/user-installable)
• Introduces new interaction metadata handling for better tracking of interaction chains
• Updates Guild fallback logic to handle cases where guild data isn't cached
