Fix Bun.serve port binding and error handling

- Add explicit hostname: '0.0.0.0' to bind all interfaces
- Add try/catch around server creation with proper error logging
- Add server error handler for runtime exceptions
- Add verification timeout to confirm server is actually listening
- Enhanced debugging to identify port binding issues

Fixes issue where server claimed success but wasn't actually listening on port 3000.
