Virtualize the TopicFeed post list

[RUKAYAT-CODER]

Overview
src/components/social/TopicFeed.tsx (lines 230-319) renders every loaded post — each a heavy article with image, links, and tags — into the DOM via infinite scroll with no virtualization, so memory and layout cost grow linearly with pages loaded. Virtualize the list to keep the DOM bounded.

Hello Maintainer, I am Nacho, a full-stack developer with experience building high performance React and Next.js applications.

I would d like to work on this issue because frontend performance optimization is an area I enjoy, especially when it involves improving the user experience for large, dynamic lists. Virtualizing long lists is an effective way to reduce memory usage, improve scrolling performance, and keep rendering efficient as more content is loaded.

I will ll implement list virtualization for the "TopicFeed" while preserving the existing infinite scroll behavior. I will ensure only the visible posts (plus a small buffer) are rendered, keeping the DOM size bounded without affecting functionality. I will also verify that images, links, tags, and scrolling behavior continue to work seamlessly and that the solution integrates cleanly with the current codebase.

I would d appreciate the opportunity to contribute. Thank you for your consideration.
