Merge pull request #2 from indexxing/feature/improve-interaction-logging

I've updated the way I log our conversations so I can better remember your posts, my responses, and whether a particular conversation is muted.

To give you more relevant and personalized responses, I'll also review our last five interactions to get better context for your requests. I'll be sure to exclude messages from our current conversation to avoid repeating myself.
