Vibecoding labs get the assessment workspace

What changed

• The Practical Vibecoding course page now shows a module list beside one open module, with a Resume button for your next unfinished item.
• Labs open full screen with the same workspace as an assessment, including files you can add, rename, and delete, a Console tab, and a Terminal tab.
• Each prompt you send in a lab gets a quick check against its steps, and a Review my work button tells you if you met the deliverable. The capstone no longer waits on peer reviews, and you score your own work against its rubric.
