fix: remove negation from rotation to match prompt semantics

Browse Source 
New prompt defines rotation_degrees as already signed:
- positive = counter-clockwise rotation
- negative = clockwise rotation

Old code negated it: rotate(-rotation_degrees), which inverted the direction.
Now: rotate(rotation_degrees) directly uses Gemini's signed value.
