Adds the species/organism layer on top of the gene foundation. GenomeTemplate carries which GeneDefs an individual has plus the per-organism base value and spread its alleles are drawn around (and an optional discrete-variant override), so the same shared GeneDef expresses different centres for different species — Generate() draws an individual, Registry() feeds breeding and trait computation. Genome.Breed gains an optional mutationChance that overrides every gene's fixed MutationChance, so a caller can drive mutation from an evolvable trait. Allele sampling (numeric spread+clamp, weighted discrete pick) is factored into a shared GeneSampling used by both Generate paths. Covered by GenomeTemplateTests (per-species centres, registry-driven breeding, mutation override on/off). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
