* Done. I've updated both the Tags section and Files section in the typeahead plugin. The changes:
1. Added `border-l-2` to all items to create a left border
2. For selected items: `border-l-brand` (orange accent color) + `bg-muted` + `text-high`
3. For unselected items: `border-l-transparent` + `hover:bg-muted` + `text-muted-foreground`
4. Removed the redundant `text-foreground` class that was conflicting with `text-high`
The selected item now has a visible orange/brand-colored left border indicator that provides clear visual feedback in both light and dark modes.
