ESLint formatter for Code Climate

An ESLint formatter that outputs lint results in the Code Climate report format, suitable for integration with Code Climate's platform. Version 2.0.1 supports ESLint >=9 and requires Node.js 20+. The v2.0.0 release switched fingerprint hashing from SHA1 to SHA256, a breaking change. It offers both a CLI formatter (--format codeclimate) and a programmatic API (toCodeClimate). Unlike generic JSON formatters, this produces a Code Climate-specific JSON structure with categories, fingerprints, and relative paths.
