fix: handle server 'error' event in listen() to prevent process crashOpenPR

Summary Fix a process crash vulnerability in the function when fails. Finding: Unhandled Error Event Crashing Process (Medium) File: , lines 25–28 Issue: The function does not attach an event handler. When fails (e.g., EADDRINUSE, EACCES, invalid arguments), Node.js emits an unhandled event, which crashes the process with . Additionally, never settles, creating a dangling unresolved promise. Fix: Added between and events Errors from are now properly propagated as promise rejections instead of crashing the process Verification ✅ Promise resolves correctly when server listens successfully ✅ Promise rejects with the error when fails ✅ Backward compatible — interface unchanged Related CWE-754: Improper Check for Unusual Conditions 🔒 Security Note for Vercel Security Team This PR fixes a process crash vulnerability. This finding may be eligible for the Vercel Open Source Bug Bounty Program** (Tier 2: $250–$5,000). Ref: https://hackerone.com/vercel-open-source
