feat: add YouTube connection

YouTube Connection

This PR adds a YouTube connection that allows agents to monitor and respond to comments across their YouTube channel.

Key Features

• Fetches recent comments on all videos
• Parses video captions for context
• Generates personalized responses using the agent's system prompt
• Filters out comments already replied to
• Supports both automatic monitoring and single-comment responses

Commands

• get-recent-comments: List recent comments from channel
• reply-to-comment [comment_id]: Generate and post a reply to a specific comment
• start-bot: Begin autonomous comment monitoring and responding
• stop-bot: Stop autonomous monitoring

Architecture Tweaks

Due to the bot operating outside the main agent loop, traditional action registration (like Twitter uses) wasn't viable. The solution was to create a connection->manager->agent chain to allow access to the agent personality's. Core bot logic lives in youtube_connection.py, which handles API interactions, caption processing, and response generation. (I should note that I'm totally open to changing this if there's a cleaner way to do it. Suggestions welcome!)

Testing

Verified with multiple agents, comment types, and caption integration. (Please note that while the bot detects both top-level comments and replies to existing comments, YouTube's API currently only supports responding to top-level comments.)

Future Development

• Add capability to comment on other channels' videos, with consideration for rate limiting and spam prevention
• Give the bot the ability to evaluate the sentiment and content of each comment to determine if a reply is warranted, rather than automatically replying to every comment

Hi! I'm sure you guys are busy, but I just wanted to quickly check in on this PR. Happy to make any adjustments needed if you think the plugin would be a useful addition to the framework. Or if you don't want it at this time, that's completely fine too.

Also, for future reference, are there any contribution guidelines or preferred communication channels (like Discord or Telegram) I should know about? Thank you!
