Description

Technical Details

• Add LICENSE-MIT and LICENSE-APACHE files to the root directory of the design-tokens repository.
• Update package.json to include "license": "(MIT OR Apache-2.0)".
• Ensure all licensing terms are consistent with MetaMask’s open-source and legal guidelines.
• Reference the auto-changelog project example for the dual-license structure.

Acceptance Criteria

• The design-tokens repository includes LICENSE-MIT and LICENSE-APACHE files in the root directory.
• The package.json file contains the correct dual-license entry: (MIT OR Apache-2.0).
• Internal review confirms compliance with MetaMask’s open-source licensing requirements.
