Rite of Returning 1.1.0

Fixes:
- Scrappers no longer become invisible if the .bbmodel is missing or fails to load.
- ScrapperRenderer now tries to use:
  assets/riteofreturning/models/entity/scrapper.bbmodel
- If the model is unavailable, it falls back to a visible phantom-style render using the Scrapper variant textures.
- Scrapper variant textures remain:
  scrapper_0.png
  scrapper_1.png
  scrapper_2.png
  scrapper_3.png
- Symbiote climb tentacle spacing is kept strict:
  each anchor must be at least 3 blocks away from the other anchors.
