fix(vagrant): head sprite_rot=-90 corrects 90° CW visual offset

head_001.png is drawn with face pointing +X (right) at rot=0, but the
look-at math assumes sprite-top (-Y) is forward. Without compensation,
head visually appears 90° clockwise off when math says 'point at mouse'.

sprite_rot=-90 on head bone aligns sprite-top with bone-forward at
render time. Body, shoulder, and arm sprites already match the
sprite-top=forward convention so no sprite_rot needed there.

Also bumps puppet dep to 0.3.3 and removes the temporary debug print.
