Rite of Returning 1.2.0

Soul Spear hand/aim fixes:
- Replaced broken raw held item model with a safe 3D hand model.
- New hand model uses a guaranteed texture path:

- Kept uploaded Soul Spear texture as:
  assets/riteofreturning/textures/item/soul_spear_uploaded.png
- Throw direction now uses the player's exact look vector.
- Projectile starts at the player's eye position.
- Projectile rotation syncs to motion.
- Sticking position is moved slightly back from the hit face so the model doesn't center itself through the block.
