fix(movement): jump works locally (airborne velocity preserved)

Browse source 
Two fixes for jump physics:
- Skip ground-snap when velocity Z > 0 (prevents immediate re-landing
  at high framerates where per-frame Z delta < 0.05 snap threshold)
- Guard apply_current_movement velocity write behind OnWalkable check
  (prevents MotionInterpreter.DoMotion from zeroing jump velocity on
  every frame while airborne)
- Guard PlayerMovementController velocity replacement behind OnWalkable
  (preserves momentum during airborne flight)

Jump works locally but server packet not yet sent (BUG-002).
Facing direction mismatch logged as BUG-003.
RunRate not verified as BUG-004.

# Rendering Rebuild from ACME
# Rendering Rebuild from ACME — COMPLETE
Port ACME's rendering pipeline to acdream. Each step produces a
visually testable result. The animation system stays unchanged (ACME
has none — ours is ported from the decompiled client).
**Status:** All 5 steps shipped 2026-04-13.
## Step 1: Port StaticObject shader + instanced rendering
The biggest performance win. Replace per-entity DrawElements with
