ESLint Formatter for GitHub Actions

An ESLint formatter that outputs warnings and errors as GitHub Actions file annotations. Version 1.1.0 is the current stable release; relatively stable with infrequent updates. It leverages GitHub Actions' annotation syntax for inline problem reporting directly in pull request diffs. Unlike other formatters (e.g., stylish, compact), this one integrates tightly with CI workflows, supporting both warnings and errors and requiring no additional configuration beyond specifying the formatter name.
