fix(BT12-Dev): A11 정령불 OffsetDistance 적용 (PD 지시 2026-05-14)

PD 보고: "정령불은 피격 범위의 offset distance가 적용되지 않고 있어"

원인: SpiritFireInstance.Update center = Player.position 그대로·
박스 시각 dbg.localPosition = zero. OffsetDistance 적용 누락.

정정 (A05·Laser 동일 패턴·signX + Vector2):
1. SpiritFireSpawner.Trigger 영역 facing sign + OffsetDistance Vector2
   offset 계산 → Init 인자로 전달 (Init signature 확장).
2. SpiritFireInstance._offset 신규 필드.
3. 박스 시각 localPosition = (_offset.x / lpx, _offset.y / lpy)
   (Player.lossyScale 보정).
4. 판정 center = Player.position + _offset (Update 매 frame).

검증 (Play 모드):
- test OffsetDistance (0, 1.5) 적용
- 박스 worldPos Δ from Player = (0, 1.50) ✓
- localPosition (0, 0.88) — Player.lossyScale.y=1.7 보정 정합

PD Inspector 실측: OffsetDistance=(0, 2)·HitboxSize=(3.4, 1.0)
정합 적용.
