gouki 738b5c4452 tweak(wish-tree): 弹幕各行速度错落,每行屏上2~3条不压着
Publish Mini Program Dev Version / publish (push) Successful in 46s
- 顶部行回到12%
- 每行不同基准速度:树桩三行26/33/40秒、顶部22秒,不再整齐划一
- 同行弹幕速度也带±20%随机错落(seeded保证渲染一致)
- 每行屏上保持约2.5条:间隔=duration/2.5,但不小于完全进入时间
  (duration*0.3,保证下一条不压着前一条)和最小间隔3秒

gouki a45004bfb2 tweak(wish-tree): 弹幕改为自然首尾相接,不再一行一条
Publish Mini Program Dev Version / publish (push) Successful in 1m3s
- 顶部行 12%→14%,树桩3行 68/73/78→70/73/76(间隔3%)
- 核心:从'一行同一时刻只一条'改为'前一条完全进入屏幕后就出下一条'
  同一时刻屏上可有多条,但首尾相接不重叠,更接近真实弹幕
- 每行发射定时器间隔=duration*0.35(完全进入屏幕约需飘总路程35%)
- 弹幕播完后从列表移除,stop时清空屏上弹幕避免残留
