Pull Request Overview

This PR refactors the dogfooding example by rebuilding the UI, modularizing Waku-related logic into services, and updating the asset pipeline.

• Overhauled webpack config to use explicit copy patterns and removed the DefinePlugin.
• Split Waku setup, message encoding/decoding, and UI rendering into separate modules.
• Rebuilt HTML/CSS to a modern, responsive layout with live filtering of messages.
