Updated Next.js from version 15.2.6 to version 16.0.7 with Turbopack support, which included critical security patches (CVE-2025-55182, CVE-2025-66478). Additionally, the following were updated to improve security and performance:

• React from version 18.3.1 to version 19.2.1
• React-DOM from version 18.3.1 to version 19.2.1
• Storybook from version 8.2.9 to version 10.1.2
• ESLint from version 8.42.0 or 9.17.0 to version 9.23.0
• TypeScript from version 5.5.4 to version 5.8.2
• typescript-eslint/eslint-plugin from version 8.4.0 to version 8.28.0
• typescript-eslint/parser from version 8.4.0 to version 8.28.0

The key changes from these upgrades include:

• Replaced next-client-cookies with js-cookie, for Next.js 16 compatibility
• Updated ESLint to flat config format (ESLint 9)
• Fixed CSS import ordering for Turbopack compatibility
• Created comprehensive Jest mocks for next-intl version 4
• Excluded Storybook and Jest files from TypeScript build
