Feature Request: Add Code Editor Theme Changer

[Sibsankar-de]

It would be helpful to have a theme changer for the code editor so users can switch between different themes (e.g., light and dark modes) based on their preference.

Expected Behavior

• Users should be able to select a theme from a dropdown or toggle.
• The editor UI should update instantly when the theme changes.

Suggested Approach

• Add a theme selector in the editor toolbar.

Additional Context

This will improve readability and overall user experience, especially for long coding sessions.
