- Add OutfitItem (extends HoldableItem): applies outfit on drop within 80px
of character body, falls back to hand slot attach if no character in range
- Add apply_outfit_item / remove_outfit / _handle_outfit_tap to Character
- Track item node refs in _outfit_item_refs for restoring visibility
- Fix animation state: reset to idle before tap handling in _on_drag_released
- Extract _ITEM_DROP_OFFSET constant (replaces magic Vector2(0,60))
- Add 5 tests in test_outfit_item.gd, 14 new tests in test_character_v2.gd
