feat(README.md): update package.json to better handle module resolution

- Replace "exports" field with "main", "module", and "browser" fields
- Ensure Node.js environment uses index.node.js
- Direct build tools supporting ES modules to use index.mjs
- Specify browser environment to replace index.node.js with index.mjs

This change improves module resolution across different environments and build tools, addressing potential issues with server-side and client-side execution in Next.js projects.
