Address PR review feedback: rename the shared string-helper package from strutil to stringsx to avoid the discouraged util suffix and the collision with the standard strings package, updating all import paths and call sites. Replace the manual wg.Add/wg.Done bookkeeping in the enrichment worker with wg.Go, which is less error-prone. Signed-off-by: Émile Ré <emile@probo.com>
