Aimbot v3: world-only vischeck

- resolve EngineTraceClient003; TraceRay (slot 4) from the eye to the exact
  selected hitbox/bone point with MASK_VISIBLE
- TRACE_WORLD_ONLY filter as requested (static props are not tested, per SDK)
- Aimbot -> Vischeck toggle, persisted as vischeck=1; when on, blocked targets
  are skipped and the next-nearest candidate is tried
- target candidates are ranked by angle; on each target the nearest visible
  selected hitbox point wins
