Summary of Changes

Hello @Umekawa, 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 integrates 'qlty' into the project's continuous integration pipeline to provide up-to-date metrics on code coverage and maintainability. This change is crucial for maintaining code quality standards, especially after the deprecation of the Code Climate API. The integration ensures that these vital statistics are automatically calculated and prominently displayed in the project's README, offering immediate visibility into the codebase's health.

Highlights

• Code Quality Integration: Introduced 'qlty' for monitoring code coverage and maintainability, replacing the previously used and now disabled Code Climate API.
• Coverage Data Format: Configured SimpleCov to output coverage data in JSON format using 'simplecov_json_formatter' to facilitate integration with 'qlty'.
• README Badges: Added new badges to the README.md file to display the 'qlty' maintainability and code coverage status directly.
• Development Dependency: Added 'simplecov_json_formatter' as a development dependency in the gemspec.

Code Review

This pull request introduces qlty for code coverage and maintainability metrics, replacing the now-disabled Code Climate integration. The changes correctly add the simplecov_json_formatter dependency, configure simplecov to output JSON reports, and update the README with new badges. The implementation is solid. I have a couple of minor suggestions to improve formatting and readability.
