Objective
Implement a minimal but correct classic JRPG battle loop:
- show battle scene with pre-rendered background
- show party/enemy status in a top HUD

game/scenes/battle/BattleScene.tscn- background renderer
- battler sprite anchors (party and enemy)
- BattleHUD (top)
- CommandMenu (bottom)
- Implement battle state machine

- Data models (minimal)
- CharacterData, EnemyData, SkillData, ItemData
- Integration
- Exploration encounter triggers transition to BattleScene
- On battle end, return to exploration at a defined spawn

- UI updates HP correctly
- Deterministic outcomes when seeded
