CAT 962 Next Gen Edit

This is the edited version of the original CAT 962 Next Gen Wheel Loader by FS Miner, reworked and improved by SafariMods for better performance, stability and balanced economy.

Main Machine (962.xml):
- Power: 55 HP -> 255 HP (fixed unrealistic stock value, real CAT 962 is ~250 HP)
- Max Speed: 40 kph -> 50 kph
- Weight & Stability: 11250 kg -> 14500 kg, lowered center of mass for better stability
- Articulation: 25° -> 38° max angle, faster steering for much better maneuverability in tight yards
- Improved suspension: more travel, stiffer springs and dampers
- Tire friction increased: less slipping with a full bucket
- Price: 325500€ -> 295000€ (balanced)
- Solver iteration increased for more stable physics

Leveler Attachment:
- Capacity: 3500L -> 5500L, hidden buffer increased
- Working Width: 3.4m -> 4.2m
- Empty speed and fill rate significantly increased for faster leveling
- Mass: 120kg -> 220kg, more stable operation

Forks Attachment:
- Mass: 450kg -> 550kg
- Improved physics simulation
- Faster fork width adjustment
