feat(vagrant-skeleton): Subterrain-style lower-body control model

Add lower_control virtual bone (reparents legs for independent orientation).
Update look_at fields: body uses "soft" target with slerp=6, head uses
"aim" target with instant snap and ±60° clamp. Rename walk.anim.json to
walk_fwd_lower.anim.json and add walk_back_lower, walk_left_lower,
walk_right_lower anims ported from substrate. Port HandleAnimationLower:
signed-angle sector selection (±45°/±135°) drives 4-directional walk anim
choice; wedge clamp sets lower_control rotation. Separate aim/soft look
targets both track raw mouse for now.
