New wf-readme workflow (grounded README creation/audit/rewrite) built on readme-crafter, good-readme and curating-readme skills. Validated with the QA harness: 302.3 -> 379.0 on the same ruler, all phases verified, no false-positive skill refs. Applied it to this repo: audit-repo.sh scan, link/TOC/em-dash validation, added CONTRIBUTING.md (gap the workflow flagged) and wired the docs.
