Pull request overview
This PR removes the deprecated ESLint eslintrc configuration format, modernizing all configs to use the flat config format exclusively. The "flat/*" prefixed configs are retained for backward compatibility but marked as deprecated.
Changes:
- Removed eslintrc exports from all configuration files (recommended.js, recommended-script.js, recommended-module.js)
- Updated primary config exports (recommended-module, recommended-script, recommended, all) to use flat config format
- Added new "mixed-esm-and-cjs" config for handling mixed module types
- Removed eslintrc test file and updated documentation generator configuration
- Updated rule documentation to reflect that all rules are now included in the "all" config

The newly introduced non-prefixed configs (recommended-module, recommended-script, recommended, mixed-esm-and-cjs, all) lack test coverage. While the deprecated "flat/*" prefixed configs have tests in tests/lib/configs/flat.js, there are no tests verifying that the new primary config names work correctly. Consider adding test coverage for these configs.
