ESLint config hudochenkov

A shared ESLint flat config package by hudochenkov, providing preset configurations for JavaScript, React, React Testing Library, and Jest. Current stable version 13.0.0 requires ESLint ^9.30.0, Node.js >=20, and runs as ESM only. It is released actively, following ESLint and plugin updates. Key differentiators: it is opinionated but modular, allowing selective use of `main`, `react`, `reactTesting`, and `jest` configs; it migrated to flat config in v10 and dropped CommonJS support; peer dependencies are extensive, and users must install them manually. This config enforces modern rules from `@stylistic/eslint-plugin`, `eslint-plugin-unicorn`, and `eslint-plugin-import`, and disables `import/no-unresolved`.
