makefile-awk-help-extractor-excludes-digit-containing-targets

The common Makefile self-documenting pattern using awk '/^[a-zA-Z_-]+:/' silently omits targets whose names contain digits (e.g., test-a11y, k8s-apply, test-cov). After adding digit-containing targets in Wave 6, make help did not list them. Fix: use awk '/^[a-zA-Z0-9_-]+:/' or equivalent \w word-char class to include alphanumeric target names.
