feat: 全部160测试通过(22s). 损伤模型RequiredExposure替代硬编码

Browse Source 
- IDamageModel.RequiredExposureSeconds(TargetType,PowerType,AerosolType)
- InertGas: 1/(0.15*sensitivity), Piston 1.5→4.44s
- ActiveMaterial: (1-burst)/residual + burst threshold
- ActiveFuel: ∫BaseRate*e^(kT)解析解
- CalcRoundsNeeded/ComputeInterceptProbability/BuildCandidates 全部调用
- 场景缩短: Piston 5km/150km/h, Jet 5km/200km/h, AirBased 10km/150km/h
- 空基 test: Unit(1500,1000), hp=0 Destroyed
