Senses stage 1: smell/touch capacities, organs, acuity + detectability genes

Foundation for the perception system. Adds Smell and Touch capacities (CapacityCalc
dependency chain x consciousness) with organs on the Quadruped body (nose->Smell,
skin->Touch; eyes/ears already give Sight/Hearing) so hediffs and organ damage
reduce them for free. New genes: acuity GeneHearing/GeneSmell/GeneTouch (radius
multipliers, default 1 if a species omits them) and detectability GeneCamouflage
(lower sight), GeneScent (raise smell), GeneNoise (raise hearing) on AnimalPhenotype.
Deer/wolf/boar/chicken get sensible values (wolf smells well, deer is alert +
dappled). cap.smell/cap.touch localized. Build + --check-content clean
(48 genes, 47 traits). Multi-sense detection + memory come next.
