Description

This PR updates the CODEOWNERS file by removing mobile developers from the component-library folder. The goal is to:

• Prevent Prop Bloat: Streamline components and avoid unnecessary complexity.
• Maintain Consistency: Ensure that we achieve 1:1 consistency across Figma, Extension, and Mobile environments.
• Reduce Tech Debt: Centralize control over merge permissions to avoid inconsistencies and maintain clean component architecture.
