Description

This PR adds a comprehensive vue-to-react-converter skill that helps developers convert Vue.js components (Composition API & Script Setup) to React components using functional components and Hooks.

What's Included

This skill provides detailed guidance for converting Vue.js code to React, covering:

• Basic conversion patterns: ref → useState, computed → useMemo, lifecycle hooks → useEffect, etc.
• Advanced patterns: slots, provide/inject, routing, animations, forms, and more
• State management conversions: Vuex → Redux Toolkit, Pinia → Zustand/Jotai
• TypeScript support: Type conversion examples and best practices
• Common pitfalls: Warnings about frequent mistakes and how to avoid them

Key Features

• Step-by-step workflow (5 clear steps from analysis to validation)
• Comprehensive reference documentation
• Side-by-side code examples (Vue vs React comparisons)
• Selection guides for choosing the right state management solution
• Best practices and reactivity model differences
