NS-23: terminal collision, nav around obstacle, agent under region 

- Add BoxShape3D to PrototypeTerminal (layer 1, walkable) so the player
  cannot pass through; matches terminal mesh size.
- Bake navigation from collision layer 1 only so the player (layer 2) is
  not merged into the mesh; reparent Player under NavigationRegion3D so
  NavigationAgent3D resolves a valid map.
- Restore nav waypoint following for long horizontal legs; keep horizontal
  steering toward next/goal so bump departure behavior stays sane.
