fix: drop old React peer support

[exKAZUu]

Summary

• restrict React and React DOM peer dependencies to React 19 via ^19.0.0
• document the supported baseline as React 19.x, Node.js 24+, and Next.js 16
• refresh Yarn lock metadata and package metadata formatting

Why

• the package only needs to support the current React major, which simplifies the support contract
• using ^19.0.0 keeps support limited to React 19 while avoiding unnecessary peer warnings for users on earlier React 19 releases

Breaking Change

• React and React DOM 16, 17, and 18 are no longer declared as supported peer dependency versions

Testing

• yarn check-for-ai
• PR CI passed

Code Review

This pull request updates the package's environment requirements and dependencies, including setting the minimum Node.js version to 24 and updating React support to version 19. It also includes a reorganization of the package.json file and updates to the documentation. A review comment suggests using a more permissive version range for React peer dependencies (^19.0.0 instead of ^19.2.5) to improve compatibility and prevent installation warnings for consumers.

Code Review

This pull request updates the package to support React 19 and Node.js 24, restricting peer dependencies to React 19 and adding a Prettier configuration. Feedback notes that the restriction of React versions is a breaking change requiring a major version bump via conventional commits, and suggests clarifying the supported React range in the README.

Code Review

This pull request updates the project's peer dependencies to require React 19.0.0, effectively dropping support for React 16, 17, and 18. The README has also been updated to reflect these changes along with new requirements for Node.js and Next.js. Feedback was provided regarding the need to explicitly mark this as a breaking change in the commit message or PR title to ensure that semantic-release triggers a major version update rather than a patch release.
