Add OpenGrep SAST workflow and security waivers file

[devin-ai-integration]

Add OpenGrep SAST Security Scanning to All 62 Zampfi Repositories

Summary

This is a comprehensive security enhancement initiative that adds standardized OpenGrep SAST (Static Application Security Testing) workflows across all 62 active repositories in the Zampfi organization. This bulk operation implements two critical security files in each repository:

1. .github/workflows/opengrep-sast.yaml - A 273-line GitHub Actions workflow that runs OpenGrep security scanning on all PRs and pushes to main
2. .security-waivers.json - An empty security waivers file ({"waivers": []}) for managing security exceptions

Current Status: 41/62 PRs created and in progress. The security workflow is designed to block PRs with critical/high security issues until they are resolved or properly waived.

Key Features:

• Comprehensive security rule coverage (TypeScript, Python, Java, Go, etc.)
• Automatic security report generation in markdown format
• Security waiver system for managing false positives
• Integration with GitHub Actions for automated scanning

Review & Testing Checklist for Human

⚠️ HIGH RISK: This affects all 62 repositories and changes how security is handled organization-wide.

• Verify security workflow isn't overly restrictive - Test that the OpenGrep SAST workflow doesn't block legitimate development. Check if the security rules are appropriate for your codebase patterns.
• Investigate unexpected CI failures - Several PRs show 2+ failed checks (beyond expected security-scan). Review connectivity-platform, data_platform, herm, and contract_extraction for non-security-related failures.
• Complete the remaining 21 PRs - Ensure all 62 repositories receive the security files. The bulk operation was interrupted at 41/62.
• Test the waiver system end-to-end - Create a test security issue, add it to .security-waivers.json, and verify it gets properly ignored by the workflow.
• Validate security scan results are actionable - Review a sample of security-scan failures to ensure they represent real issues and not overwhelming false positives.

Recommended Test Plan:

1. Pick 2-3 representative repositories with different tech stacks
2. Create test PRs that should trigger security issues
3. Verify the security workflow blocks appropriately
4. Test adding waivers and confirm they work
5. Check that normal development PRs aren't blocked

Notes

• Session Details: Requested by shashvat@zamp.ai | Session: https://app.devin.ai/sessions/6b8a3486391f45e0b66ec32758e5f7da
• Expected Behavior: The "security-scan" CI failures are expected and indicate the workflow is correctly identifying security issues
• Trailing Whitespace Fix: Applied to source file but may need to be propagated to existing branches
• Pantheon Repository: Failed during bulk operation due to pre-commit hook issues with trailing whitespace
• Success Indicator: payments-sdk PR shows all checks passed, proving the workflow functions correctly when no security issues are found

⚠️ Critical: This security workflow will block PRs with critical/high severity issues. Ensure your team understands how to use the waiver system before merging these changes.
