Title: Performance Improvement: Social Panel

Author: nostr:npub1dww6jgxykmkt7tqjqx985tg58dxlm7v83sa743578xa4j7zpe3hql6pdnf

Needs to speed up Social Panel's rendering.

Currently, 150K events require ~100ms to process per `render` call. It's too slow. Need to make it to sub 25ms again.

Remember, our goal is to handle 1 million events locally under 25ms.
