feat(BT12-Dev): PD 4 지시 — Projectile 거리 제한·벽 충돌·특성 가시화·Icon UI 매핑 (MCP 자율)

PD 지시 (2026-05-10):
1. 투사체 종류 영역 일정 거리 영역 소멸 (Camera width × 1.5)
2. 레이저 외 투사체 영역 벽 충돌 시 소멸
3. 스킬 특성 영역 컨셉 동작
4. 스킬 선택 UI 영역 아이콘 노출

본 PM MCP 자율 진행:

==== PD #1: 거리 제한 ====
Projectile.Initialize:
- _spawnPosition 저장
- _maxRange = Camera.orthographicSize × 2 × aspect × 1.5 (가로 × 1.5)
Projectile.Update:
- Distance(transform.position, _spawnPosition) >= _maxRange → SelfDestruct

==== PD #2: 벽 충돌 ====
Projectile.OnTriggerEnter2D:
- isEnemy 처리 → hit 후 SelfDestruct·return
- Layer 0 (Default·Ground) || Layer 16 (Foreground·발판) → SelfDestruct
- 본 Projectile 영역 = A 카테고리 (레이저 영역 영역 X) — 모든 영역 SelfDestruct 정합

==== PD #3: 특성 가시화 ====
StatusApplier·EnemyStateComponents 영역 — DoT·Stun·Slow·Knockback·DebuffStack 영역 영역 정합 영역.
근본 영역 — Enemy hp 4·damage 5·1hit 즉사 → 효과 시각 X.
정정 — Enemy.prefab maxHearts 1→5 (maxHP 4→20) — A02 DoT·A03 Stun·A14 Slow 영역 4 hit 영역 영역 영역.

==== PD #4: Icon UI ====
SkillCardSlot _icon 매핑 X 영역 — BannerFrame04_Divided 자식 영역 SkillIcon GameObject 신규 추가 + Image 컴포넌트
- anchorMin·max (0.5, 0.7)·sizeDelta (120, 120)·preserveAspect true
- 3 슬롯 영역 _icon 필드 매핑 정합
