Rite of Returning 1.2.9

Soul Spear projectile alignment:
- Keeps Soul Spear (3).bbmodel byte-for-byte and unmodified.
- Keeps the flat-plane / zero-area face skipping renderer change for the spear-tip texture.
- Keeps the groups-loader visibility fix.
- Adjusted only the thrown projectile renderer transform so the model sits centered on the projectile hitbox.
- Fixes the thrown model appearing down-left from the hitbox.
- Keeps exact look-vector throw, mob bounce/fall behavior, ground stick exact orientation, and trident tags.
