This commit implements drag-and-drop functionality for sidebar nodes,
adding visual feedback via highlight styling when dragging over
valid drop targets. The CSS introduces new classes to style
drop indicators using the lora-accent color scheme, while the JS
adds event handlers to manage drag operations and update the UI
state accordingly. This improves user interaction by providing
clear visual cues for valid drop areas during file operations.
