@claude Add a dark mode toggle button to the Node-RED editor header (next to the deploy button). When toggled, it should switch the entire editor interface between light and dark themes. Store the preference in localStorage so it persists across sessions. Make sure all UI components (palette, workspace, sidebar, dialogs) properly support both themes with good contrast ratios.
