fix(vagrant): iteration — body+head look-at, WASD-driven leg-facing, idle-collapse

Browse Source 
- humanoid.rig.json: root removed from upper track; body look_at + slow speed
  (180 deg/s, lazy); head fast speed (480 deg/s) + +-90 deg limits; puppet
  dep bumped to 0.3.1
- animations/idle_lower.anim.json (NEW): leg+foot scl=[mirror, 0] keeps legs
  invisible at idle (locomotion skips animated bones; foot cascade zeros out)
- init.lua: set_procedural 'facing' callback writes root.rot from
  last_walk_rot_deg each frame; WASD-vector updates last_walk_rot_deg
  via atan(dx, -dy); idle_lower played parallel to idle, stopped during walk
