OSWS Weapon Inertia

This mod overhauls weapon handling to better reflect real-world firearm behavior. It introduces physical-based recoil springs, turn inertia, tremor, deadzone aiming, and smoother ADS transitions. Recoil scales dynamically with firemode and is reduced when using deployed bipods, rewarding proper weapon support. The goal is a more grounded, weighty, and skill-based shooting experience without removing responsiveness or playability.
