Vercel Reverse Proxy Test

Testing path-based routing for UPF-4358

• /upflowy/* → Proxied to Upflowy origin (simulated with httpbin)
• /get → Proxied to customer origin (httpbin JSON)
• /html → Proxied to customer origin (httpbin HTML)
• /headers → Shows request headers at origin

Test result: If you see this page, the middleware is working!
