fix(vagrant): walk anim — slow to 0.5x, no leg.scl_y sign flip

Browse Source 
User manual-test feedback after iteration-3 hip-stable + leg-rotation
fixes:

1. Animation too fast for actual map traversal → play walk_fwd_lower
   and walk_upper with speed=0.5 (effective 1.6s cycle, was 0.8s).
2. Second half visually broken → was substrate's sign-flip trick where
   leg.scl_y goes +1 (opposite of rest -1) and foot.pos.y flips
   negative. Cascade foot.world.scl_y = +1 * -1 = -1 → foot rendered
   Y-flipped. User: 'die füße ... darf hier die skalierung nicht negativ
   werden'.

   New cycle: each half extends ONE leg (scl_y=-1 matching rest) while
   the other stays at scl_y=0 (collapsed/invisible). foot.world.scl_y
   never goes negative — only [0, +1]. Alternating-leg gait. Substrate
   first-half preserved verbatim; second-half mirrors with role swap.
