改进 / Improvements

• 函数轨迹运动逻辑重写 / Function Trajectory Motion Rewrite
  彻底重构了弹射物的运动计算方式。现在水平速度保持恒定，垂直速度根据目标高度动态调整，消除了之前正弦曲线等函数运动中幅度逐渐衰减的问题。
  Completely rewrote the projectile motion calculation. Horizontal velocity is now constant, while vertical velocity adjusts dynamically based on the target height. This eliminates the amplitude attenuation issue previously observed in sinusoidal and other function trajectories.

• 垂直速度限制 / Vertical Speed Limiting
  引入了 MAX_VERTICAL_SPEED 限制（默认 1.2），防止因函数值突变导致弹射物瞬间飞过头顶。
  Introduced MAX_VERTICAL_SPEED limit (default 1.2) to prevent projectiles from overshooting violently due to sudden function value changes.
