Node.js v24 emits DEP0169 (url.parse()) and DEP0040 (punycode) deprecation warnings from dependencies like Express 4 and URL-processing libraries. These warnings are captured by Sentry as error-level console breadcrumbs, creating noise in performance transaction monitoring. Filter them out using beforeBreadcrumb to keep Sentry data clean.
