feedback1d WN: 暴鸰 hovers through its cast and speeds up when it ends; 掠海漂移体's crawl in UnitInfo.form

- Official Boomb ability: the cast finishes once the bomb has landed and at
  least 0.667 s after the release (_fireAttackFinishWhenProjectileInvalid,
  _minPostDelayWhenProjectileInvalid), then buff bomb_s gives the speed
  (PRTS "技能结束后移速最终提升至200%"). kitBombd: BOMBD_POST_DELAY; the speed-up
  at the cast end instead of the landing; the drone holds still until then,
  like the engine's pause for an enemy attack clip.
- The bomb-less look still starts at the release: the view begins the *_2
  clips after the Attack clip (the official end clip Idle_2); at the cast end
  it would draw the bomb back for a frame.
- kitSyufo records e.form = 'crawl', so a field opened later draws it crawling.
