Phase B: plant genome drives growth via environment suitability

Browse Source 
Bump the engine submodule to d0104df (Suitability.Gaussian). Each plant now
carries a diploid PlantGenome (allele pairs, phenotype = allele average) seeded
from a per-species GenomeDef baseline at spawn. PlantGrowthSystem replaces the
flat fertility multiplier with vigor times a product of Gaussian suitabilities
for light (day/night), temperature (climate season) and the cell's fertility —
so plants grow faster in their preferred light/warmth/soil and crawl outside it.
Genomes are visible and editable in the ECS inspector. plants.json carries the
species genomes.
