Add HTTP/SSE test scripts demonstrating remote server usage

New Scripts:
- demo-http-api.js: Simple demo showing HTTP server is accessible TODAY
- test-http-mcp.js: Full MCP protocol test over HTTP/SSE
- npm run test:http: Run HTTP/SSE MCP protocol tests

Purpose:
Demonstrates that while major AI tools don't support HTTP/SSE MCP yet,
the deployed server IS accessible and usable right now for:
- Custom integrations (web apps, bots, extensions)
- Testing the MCP protocol over HTTP
- Future-proofing for when tools add support

Usage:
  node demo-http-api.js        # Quick demo (works now)
  npm run test:http            # Full MCP protocol test

Dev Dependencies Added:
- eventsource: For SSE client connections
- node-fetch: For HTTP requests

Shows Real Value:
- Server is deployed and working at hpr-knowledge-base.onrender.com
- Can be integrated into custom apps TODAY
- Ready for future MCP client adoption
- Not just waiting for tool support

This addresses the question: "Did I build something nothing supports?"
Answer: No! It's accessible now for custom code, and ready for the future.
