fix clip-overwrite class bug: 10 lessons re-sliced with unique per-item clips (same filename had been reused for different time ranges — each cut overwrote the last, playing wrong audio); 27 master activities rebuilt from fixed sources (snap-back had collapsed differing texts into repeats of item 1). Tester-reported: Book 11 lesson 1-7 Present Perfect voiceover/text mismatch
