Analysis: All GitHub workflows already have minimum token permissions

[Copilot]

This PR analyzes all GitHub workflow files in the repository to verify compliance with OpenSSF Scorecard Token-Permissions recommendations.

Analysis Results

After thorough verification using the scripts provided in the issue, all 9 GitHub workflow files are already fully compliant with the minimum token permissions requirements:

✅ benchmark.yml - Has permissions: contents: read + job-level pull-requests: write
✅ ci.yml - Has permissions: contents: read (no additional permissions needed)
✅ codeql-analysis.yml - Has permissions: contents: read + job-level security-events: write
✅ fossa.yml - Has permissions: contents: read (no additional permissions needed)
✅ integration_tests.yml - Has permissions: contents: read (no additional permissions needed)
✅ markdown-link-check.yml - Has permissions: contents: read (no additional permissions needed)
✅ ossf-scorecard.yml - Has permissions: contents: read + job-level security-events: write and id-token: write
✅ pr_naming.yml - Has permissions: contents: read (no additional permissions needed)
✅ semver.yml - Has permissions: contents: read (no additional permissions needed)

Verification Process

1. Root-level permissions: All workflows have proper permissions: contents: read blocks
2. Job-level permissions: Correctly applied only where needed (CodeQL, OSSF Scorecard, and benchmark jobs)
3. Formatting compliance: All workflows follow the correct blank line formatting rules
4. No local reusable workflows: Confirmed no additional workflow files require analysis

Conclusion

The repository already implements minimum token permissions correctly according to OpenSSF Scorecard recommendations. The previous maintainers have proactively addressed this security requirement, and no changes are necessary.

Fixes #7.
