Rite of Returning 1.0.98

Added Scrappers:
- Flying fireball mob.
- Spawns naturally in Nether biomes.
- 4 texture variants.
- 50 health.
- 16 attack damage.
- Shoots fireballs at players.
- Wild Scrappers retreat when players get within 10 blocks.
- Wild Scrappers try to stay around 20 blocks away when retreating.
- If a player gets within 5 blocks, Scrappers switch to melee.
- Tamable with Flame Souls.
- Tamed Scrappers follow their owner, heal from Flame Souls, and attack the owner's target/attacker.
- Animation names reserved for model integration:
  - Idle
  - Walking
  - flying

Note:
- No Scrapper .bbmodel file was available in this workspace, so this patch uses a safe PhantomRenderer fallback with four Scrapper texture slots.
