Add activity feed API

[343dev]

TL;DR

Added a basic Express server with a mock activity feed endpoint.

What changed?

Created a new server.js file in the graphite-demo directory that:

• Sets up an Express server running on port 3000
• Includes mock data for an activity feed with 3 sample entries
• Implements a GET endpoint at /feed that returns the activity feed data as JSON

How to test?

1. Install dependencies: npm install express
2. Start the server: node graphite-demo/server.js
3. Access the endpoint in your browser or with curl: curl http://localhost:3000/feed
4. Verify that the response contains the mock activity feed data in JSON format

Why make this change?

This provides a simple backend API for the graphite demo application to fetch activity feed data, enabling frontend development to proceed with realistic data without requiring a full backend implementation.
