Summary of Changes

Hello @jbampton, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on enhancing code quality and consistency by integrating the official Rubocop linter into the pre-commit hook system. This change streamlines the enforcement of Ruby coding standards and replaces a previously removed Rubocop setup, ensuring continuous code style adherence.

Highlights

• Pre-commit Hook Integration: I've integrated the official Rubocop linter (v1.77.0) into the project's .pre-commit-config.yaml. This ensures that Ruby code style checks are automatically performed before commits, standardizing code quality.
• Rubocop Configuration: The newly added Rubocop pre-commit hook is configured to use a specific configuration file located at .github/linters/.rubocop.yml, allowing for centralized and version-controlled style guidelines.

Code Review

This pull request adds the official RuboCop pre-commit hook, replacing a previously used one. The change is straightforward, but I've identified a critical issue with an invalid Git revision for the hook that would prevent it from working. I've also suggested improvements for efficiency by limiting the hook to Ruby files and for conciseness by removing optional fields. A code suggestion is provided to address all these points.
