Plant–herbivore coevolution + RimWorld-style health capacities

Adds the first plant↔animal coupling beyond "herbivore eats plant": a toxin/
thorns ↔ tolerance arms race built on the existing gene + hediff engines, plus
the fuller RimWorld capacity set on the health scaffold.

Coevolution C1 — plant defense → poisons/injures the eater:
- Plant genes GeneToxicity/GeneThorns/GenePalatability (GenomeDef + PlantSet
  template + PlantPhenotype); animal gene GeneToxinTolerance.
- Hediff Poisoned (non-progressing; grows from eating via HealthState.Intensify,
  immunity heals it, overdose is lethal).
- AnimalActionSystem.ApplyPlantDefense on each bite: poison dose =
  toxicity × (1 − tolerance); thorns → ApplyInjury (reuses predator-cluster).
- Cost of defense: PlantGrowthSystem growth ×= DefenseGrowthFactor()
  (1 − 0.4·toxicity − 0.3·thorns) — without a cost defense would max out and
  coevolution would stall.
- Showcase: cactus thorns, poisonous mushroom; grass starts clean so toxicity
  can evolve on the staple. Deer/boar get small starting tolerance.

Coevolution C2 — discrimination + the other half of the arms race:
- Smart foraging (reuses A7 intelligence gating): herbivores with effective
  intelligence ≥ tier-4 weigh plants by palatability − perceived-toxin −
  distance; reflex grazers (or sick animals with dropped consciousness) eat the
  nearest plant and risk poison.
- Cost of tolerance: detox raises metabolism (need decay ×= 1 + 0.5·tolerance),
  closing the arms race so tolerance doesn't fix at 1.
- popstats reports mean toxinTolerance and a plants line (mean toxicity/thorns/
  palatability) to watch the drift.

Health capacities (RimWorld parity, user-requested):
- New capacities BloodFiltration/Hearing/Talking/Eating; CapacityCalc rewritten
  to emit only capacities the body declares (a destroyed organ still shows 0%)
  with the full dependency chain (blood → pumping/breathing/filtration →
  consciousness → moving/sight/hearing/talking/eating, digestion).
- Quadruped body gains kidneys + liver (filtration), ears (hearing), jaw/tongue
  (eating/talking). Inspector health tab lists all of a body's capacities.

Localization (ru/en) for new genes' defense line, Poisoned, and the new
capacity labels. Build + --check-content clean (11 def types, 40 genes,
39 traits). Not GUI-verified (headless can't render the world scene).
