"""
CI/CD Pipeline Health Checker
Checks pipeline status, recent failures, and provides insights for GitHub Actions,
GitLab CI, and other platforms. Identifies failing workflows, slow pipelines,
and provides actionable recommendations.
Usage:
# GitHub Actions
python3 ci_health.py --platform github --repo owner/repo
# GitLab CI
python3 ci_health.py --platform gitlab --project-id 12345 --token <token>
# Check specific workflow/pipeline
python3 ci_health.py --platform github --repo owner/repo --workflow ci.yml
