Subject: [PATCH] harden(ci): concurrency-cancel guard on canonical check
 workflows

Redistributes the merged hyperpolymath/standards#122 canonical fix:
adds concurrency{cancel-in-progress:true} to read-only check workflows
(and scopes affinescript-verify push to [main,master]) so re-pushes /
rebased PRs do not pile up queued runs against the shared account-wide
Actions concurrency pool. Read-only checks only; zero coverage lost.

Files: scorecard.yml governance.yml codeql.yml secret-scanner.yml
