Social species (deer 0.8, wolf 0.6, chicken 0.55, boar 0.3) now school together:
AnimalDecisionSystem scans nearby same-species neighbours (HerdScan) and, when
wandering, a lone social animal steers toward the herd centroid (cohesion) while
close members just mill about (separation). "Safety in numbers" shrinks the
threat-detection radius in a group, so herded prey are calmer and scatter less.
Asocial animals (sociability < 0.3) keep the old random wander. GeneSociability
+ trait; `animal` console prints insulation/sociability. Build + --check-content
clean (42 genes, 41 traits). Not GUI-verified.
