Create Nuclear Armaments

Fixed mushroom cloud render-buffer handling to improve fireball and smoke rendering stability. Optimized blast scans to skip unloaded chunks and positions outside world build limits, while reducing crater-rim candidate allocation and sorting overhead. Added shared per-dimension budgets for edge fractures and fallout processing, preventing simultaneous detonations from multiplying their processing budgets. Fallout scans now resume across ticks, with rotating job order to prevent individual jobs from monopolizing processing time. Residual radiation zones now persist with world saves and resume after world reloads or server restarts. Time spent offline does not consume their remaining duration. Improved entity damage and radiation queries across intersecting Sable physics structures. Cached optional compatibility entry points, added compatibility failure diagnostics, and limited repeated rendering error logs. Updated the development environment to Create Nuclear 2.0.0. Removed the unused billetCost configuration option. Crafting costs remain defined by recipes.
