[feat] Update to use URLPattern

https://developer.mozilla.org/en-US/docs/Web/API/URL_Pattern_API

This is a node native feature as of v24 with support for regex groups, which path-to-regexp removed recently. Migrating to URLPattern will add back regex groups, but only for newer versions of node.

Start by reading the linked URLPattern API documentation and then inspect how path-match currently uses path-to-regexp. Identify the route-matching entry point and any existing tests before assessing the migration. Done means path-match uses URLPattern while accounting for the Node.js version requirement and restoring regex-group support.
