Bluesky keyword alerts

Custom notifications for when you, your company, or anything you care about is mentioned on Bluesky.

1. Query

Specify your queries in the queries variable.

Bluesky doesn't support boolean OR yet so we do a separate search for each keyword.

2. Notification

Below I'm sending these mentions to a private channel in our company Discord, but you can customize that to whatever you want, @std/email, Slack, Telegram, whatever.
