Implement complete world-generation-realist system with volcanic physics and region fusion
- Create volcanic system: Volcano.h, VolcanoFactory.h, VolcanoImpact.h with realistic lifecycle modeling
- Add PlanetaryDifferentiationFunction.h for gravitational material separation (regions → core)
- Implement CoolingPhaseFunction.h with dual influences (core + surface temperature)
- Create UniversalRegionFusionFunction.h as template with duck typing for type-safe fusion
- Add ResourceRegion.h, TectonicRegion.h, ClimateRegion.h with unified fusion interface
- Update Regular_world.json with Phase 0 initialization and volcanic/cooling configurations
- Add melting_point_celsius to all resources for volcanic composition filtering
- Implement ResourceRegistry and RandomGenerator singletons for performance
- Scale system for realistic quantities: uint64_t gameplay, uint128_t planetary core
