Complete OpenSSF Best Practices badge checklist

[AdmilsonCossa]

Goal

Complete the external OpenSSF Best Practices checklist and add the badge only after the project entry exists and the checklist status is real.

Evidence to link

• README.md
• SECURITY.md
• CONTRIBUTING.md
• CODE_OF_CONDUCT.md
• LICENSE
• evidence/claims.json
• evidence/README.md
• .github/workflows/ci.yml
• .github/workflows/codeql.yml
• .github/workflows/scorecard.yml
• .github/workflows/release-provenance.yml
• .github/dependabot.yml
• latest GitHub release

Rule

Do not add a passing badge to the README until the OpenSSF project entry exists and the badge URL is public.
