[HenriqueLimas]

Parent: #794

Description

Migrate @ebay/ui-core-react/ebay-toggle-button-group to @evo-web/react/toggle-button-group.

Use the repository's Evo React migration guidance.

Goals

• Preserve semantic HTML, Skin/BEM styling, accessibility behavior, keyboard support, RTL behavior, and pass-through attributes.
• Align the public API with the corresponding Evo Marko contract without carrying forward obsolete React workarounds.
• Follow React 19 and @evo-web/react package conventions.

Acceptance criteria

• Uses named exports, native React 19 ref props, and no forwardRef, FC, or default exports.
• Imports the appropriate Skin .mjs module directly.
• Avoids React.Children inspection; composition uses explicit components/context where needed.
• Public custom props and object fields have JSDoc and follow Evo accessibility naming conventions.
• Includes browser interaction tests and SSR snapshot coverage.
• Includes Storybook documentation and a minimal component README.
• Updates consumer migration guidance in evo-app-migrate-react.
• Includes an @evo-web/react changeset.
• Meets WCAG 2.2 AA and supports keyboard use and RTL.
• npm run build passes.
