fix: esm-only compatibility support issue #9

[robertsoniv]

📌 Description

This PR addresses the ESM/CommonJS compatibility issue in Sitecore Cloud-SDK packages that prevents their use in modern JavaScript frameworks and ESM-only projects. The changes ensure all packages work seamlessly in both ESM and CommonJS environments while maintaining backward compatibility.

Key Changes:

• Updated package.json exports: Implemented proper conditional exports syntax with import/require conditions for all packages
• Added module type declaration: Added "type": "module" to all package.json files to properly declare ESM support
• Fixed ESM wrapper files: Removed invalid 'use strict'; statements from ESM wrapper files
• Enhanced TypeScript configuration: Ensured proper dual build outputs for both module systems
• Maintained backward compatibility: All existing CommonJS usage patterns continue to work

Technical Implementation:

• Modified exports field in package.json to use proper conditional export syntax
• Updated ESM wrapper files (browser.js, server.js, internal.js) to remove CommonJS-specific code
• Ensured cross-package dependencies work correctly in both module systems
• Verified browser-specific imports function properly in ESM-only projects

This fix resolves module resolution errors like Cannot find module '@sitecore-cloudsdk/events/browser' that occur in projects with "type": "module" in package.json, enabling adoption in modern frameworks like TanStack Start, Vite, and Next.js App Router.
