Kinematics: - CalculateLaunchAngle/ParabolicTimeOfFlight/ParabolicShellTime: 移除静默钳位和 45° 回退，输入无效直接抛异常 - 新增 ComputeParabolicRange(v₀,θ,Δy) → (射程,飞行时间) — 正问题 - 新增 ParabolicApex(v₀,θ) → (顶点高度,顶点时间) - ParabolicShellTime 改为委托，不重复实现 MunitionEntity: - launchAngle 必须由方案提供，不再反算 - _flightDuration 用 ComputeParabolicRange 正算 - 删除死代码 CommandFlyTo / 「到达投放点」路径 DefensePlanner: - 地基用 InterceptCalculator 的 shellTime，不再用 ParabolicShellTime 反算 SimulationEngine: - 删除空基「到达投放点」死代码 Tests: 240 通过 (KinematicsTests 38, DefensePlannerTests 36, SimulationEngineTests 12, MunitionEntityTests 3)
