Added aligned wind fronts and directional shelter

I aligned the wind-front visuals with the direction of the weather. Moving haze and particles now belong to the same passing front instead of suggesting conflicting wind directions.

The fronts last longer and apply gentler damage, with directional shelter behind substantial terrain, buildings and tall vehicles. Existing saved settings remain intact rather than being rewritten to match a new-session default.

“Longer, gentler wind fronts use matching haze and particle motion, with shelter behind substantial terrain and structures.”

The clips use an explicitly initialized native front in the desert. They show its current weather presentation; shelter and damage rules are verified separately in development evidence, rather than claimed as a filmed before-and-after damage trial.
