Code Review

This pull request introduces Jotai for state management by adding its provider to the root layout. While the implementation is straightforward, it raises an architectural concern as the project already uses Zustand. My review includes a suggestion to re-evaluate the need for a second state management library to avoid increasing bundle size and complexity. I've also included a minor suggestion to improve import ordering for better code consistency.

Pull request overview

This PR adds the Jotai Provider to the application's root layout, enabling centralized state management using Jotai atoms throughout the application. This is necessary to support existing Jotai usage (e.g., in web/context/i18n.ts) and future atom-based state management.

• Wraps the component tree with JotaiProvider at the root level
• Adds the process import from 'node:process'
