Move library collections as a group and map v2 identity refs.

Collapsed collection actions now move, rename, delete, and rerun every part so chains stay together. Identity mode follows the v2u3 Ref2VA picture wiring.

+The subject from <Picture 1> walks slowly through the path, glancing toward camera-left in awe. She turns slightly, speaking softly: "Look at the way the light hits the trees."

+[AUDIO CUES]
+Ambient forest breeze, soft footsteps on twigs, warm cinematic background strings.`
