This commit introduces a theme switcher component in the header, allowing users to toggle between light and dark modes. The changes include: - Added a new `ThemeSwitcher` component in `components/header/theme-switcher.tsx` that handles the theme switching logic and UI. - Integrated the `ThemeSwitcher` component into the `HeaderToolbar` component. - Updated the global CSS file (`app/globals.css`) to include styles for the light mode. - Initialized the theme based on user's previous preference or system preference. - Saved the user's theme preference in the browser's local storage for persistence. These changes provide a better user experience by allowing users to switch between light and dark modes, which can improve readability and accessibility, especially in different lighting conditions.
