Boss手感强化：钢琴5倍速/长条弹偏转/全员上下浮动/突击节奏调整/原种翅膀上移

- 激光钢琴：落地55帧(0.9s)即开火（原5s空窗）；攻击密度46->609束/10s(13倍)；四模式10秒内全部轮换；单键hotT3->1tick、mainT6->2、模式间隔(24/40)->(8/14)
- 长条敌弹(dartS/dartB/dartP)按飞行方向偏转渲染，dartS白色尖端朝运动方向
- 除钢琴外所有Boss增加上下浮动(ty±12/宽体±8)，左右移动速度0.008->0.013
- 暗黑突击：冲撞间隔70->105帧(+50%)；空闲移动速度0.021->0.034、y浮动0.013/15->0.021/18；空闲小攻击频率x2(minorT双倍递减)
- 太空原种：翅膀由下移10px改为上移12px（之前理解反了）
