/**
* Name: Bluesky Connector
* Description: Post to Bluesky
* Version: 1.1
* Author: Michael Vogel <https://pirati.ca/profile/heluecht>
*
* @todo
* Nice to have:
* - Probing for contacts
*
* Need more information:
* - only fetch new posts
* - detect contact relations
* - receive likes
* - follow contacts
* - unfollow contacts
*
* Possible but less important:
* - Block contacts
* - unblock contacts
* - mute contacts
* - unmute contacts
