DG: Natural Reproduction

Added & Optimized

• Zero-Allocation Spatial Partitioning & High-Mob Density Throttling ([BL-NR-005]):
  • Staggered 100-Tick (5-second) Modulo: Distributed autonomous livestock breeding checks across tick cycles ((id + gameTime) % 100 == 0) with proportional probability scaling (rate / 100), reducing server AI check overhead by over 95%.
  • Fast-Fail Probability Ordering: Random reproduction chance is rolled before any block or entity scans occur, skipping 99.9% of heavy world interactions in constant $O(1)$ time.
  • SpatialBreedingCacheHelper: Created single-purpose spatial cache managing sub-chunk entity density counts (100-tick TTL) and pasture enrichment evaluation (200-tick TTL), eliminating redundant bounding-box entity scans and block state iterations across neighboring livestock.
  • Compact Pasture Scan Bounds: Optimized pasture scanning bounding box from 25x9x25 down to a compact 17x7x17 enclosure radius ($2,023$ blocks).
• Better Dogs Synergy & Tamed Pet Protection (AnimalBreedingMixin):
  • Tamed Animals Autonomous Breeding Exemption: Tamed dogs and pets never breed autonomously in the wild without explicit player interaction.
  • Instant Vanilla Birth Delivery: Manual breeding of tamed dogs immediately delivers vanilla/Better Dogs litters (1–4 pups, personality DNA, scale alleles) with zero forced gestation delays.
  • Herd Flocking Scoping: Restricted FollowHerdLeaderGoal strictly to pastoral livestock, allowing Better Dogs pack alpha leadership (WildWolfFollowLeaderGoal) to operate exclusively on wolves.
• Cooperative Herd Leader Caching (HerdSocialHelper): Implemented spatial chunk caching (LEADER_CACHE) caching elected Alpha leaders for 10 seconds (200 ticks), eliminating hundreds of redundant 24-block bounding box queries per second across loaded chunks.
