refactor(assets): move sprite renderer to standalone project at renderer/

Separates the 3D-to-2D render pipeline from the game client into its
own minimal Godot project. No autoloads, no plugins, no game code —
just the render scene, models, textures, and export script. Eliminates
SimBridge parse errors and gdUnit4 scanning during renders.

 ### Troubleshooting
 
 - **No output files**: Godot needs a display. If running headless, prefix with `xvfb-run`.
-- **Model not found**: Check the model .tscn exists in `models/` directory.
+- **Model not found**: Check the model .tscn exists in `renderer/models/`.
 - **Godot not found**: Pass path as second arg: `render.sh wall_structural /path/to/godot`
 
 ### Adding New Models
