I think this might be better for CI/CD pipeline and locally, - see PR #85

• Runs pre-commit checks automatically on both:
  • Local commits (through git hooks)
  • GitHub Actions (on PRs and pushes)
• Runs on local repository clones without requiring Python/pre-commit package
• Sorts entries by name (case-insensitive)
• Deduplicates URLs automatically and reports removed duplicates to STDERR
• Reports case-insensitive duplicate Names to STDERR (but keeps them)
• All logs may be easily read and action taken on them.
• Allows commits to proceed even with warnings
• Easy setup:
  • GitHub Actions workflow runs automatically
  • Local setup needs just 3 commands (see README)

The script is stored in .github/scripts/ following GitHub best practices and uses pure bash/awk for maximum compatibility.
