Use composition-patterns to let AI write maintainable React composite code

# Translation Result: This article introduces Vercel's Agent Skill **composition-patterns (vercel-composition-patterns, v1.0.0)**: it uses composite components, lifted state and explicit variants to avoid the proliferation of boolean props, covering four types of rules: architecture, state, implementation patterns and React 19 API. The article explains how to install it into tools such as Cursor / Claude Code / Codex via `npx skills`, and provides official example-level refactoring and Context interface usage cases.
