feat: Implement CI/CD pipeline

[aRustyDev]

Overview

Implementing a comprehensive CI/CD pipeline to automate quality assurance and security scanning for the pre-commit-hooks repository.

Background

The repository was operating at an Initial maturity level (1/5) with no automated CI/CD processes. A comprehensive assessment identified critical gaps in automation, testing, and security.

Implementation Progress

✅ Completed

• CI/CD Assessment Report generated
• Basic GitHub Actions CI workflow (.github/workflows/ci.yml)
• Security scanning workflow (.github/workflows/security.yml)
• Bats testing framework setup
• Sample tests for hooks
• Dependabot configuration
• SECURITY.md policy
• Branch protection guidelines

🚧 In Progress

• Verify CI/CD pipeline runs successfully
• Configure branch protection rules

📋 Next Steps

• Add tests for all remaining hooks
• Set up code coverage reporting
• Create hook development guide
• Implement release automation
