This PR improves the accessibility and user experience of the sidebar folder links by separating the navigation and toggle functionality into distinct interactive elements.

Key Changes:

• Separated the folder link and toggle button into distinct elements for clearer interaction patterns
• Added proper aria-label attributes for screen readers to indicate expand/collapse actions
• Improved visual feedback with hover states on the toggle button

   • Verify behavior when a folder is both active and collapsed
