Summary of Changes

Hello @li-jia-nan, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on a significant performance optimization by replacing the classnames utility with clsx. This migration involves updating the project's dependencies and refactoring all relevant code to utilize the new library for dynamic CSS class generation. The change is expected to result in a more efficient codebase and potentially a smaller bundle size. Additionally, the update includes a minor adjustment to the .gitignore file to accommodate pnpm-lock.yaml, suggesting an expansion of supported package managers.

Highlights

• Dependency Migration: The classnames utility library has been uninstalled and replaced with clsx across the entire project, including dependencies in package.json and type definitions.
• Code Refactoring: All instances of classNames(...) in source files, documentation examples, and test files have been updated to use clsx(...) for constructing CSS class strings.
• Performance Improvement: This change is aimed at improving performance, as clsx is generally known for being a faster and smaller alternative to classnames.
• PNPM Support: The .gitignore file has been updated to include pnpm-lock.yaml, indicating potential adoption or support for pnpm as a package manager.
