Fix 3 bugs: equip crash, enchantment not processing, spire spell casting

Bug 1: EquipmentTab handleEquip was passing useCombatStore to equipItem()
which needs the crafting store (has equipmentInstances/equippedInstances).
Fixed by using useCraftingStore instead.

Bug 2: processCraftingTick() from crafting-slice.ts was never called in the
game tick loop. Added call in tick-logic.ts when currentAction is
'design'/'prepare'/'enchant'/'craft' so enchantment progress advances.

Bug 3: equipmentSpellStates was initialized as [] and never populated from
equipped items. Added logic in tick-logic.ts to build equipmentSpellStates
from active equipment spells when climbing (currentAction === 'climb').

+Found: 8 circular chain(s) — these MUST be fixed before modifying involved files.
+
+1. Processed 161 files (4.4s) (31 warnings)
+2. 1) data/equipment/index.ts > data/equipment/utils.ts
+3. 2) data/golems/index.ts > data/golems/utils.ts
+4. 3) stores/combat-actions.ts > stores/combatStore.ts
+5. 4) stores/combatStore.ts > stores/gameStore.ts
+6. 5) stores/combatStore.ts > stores/gameStore.ts > stores/gameActions.ts
+7. 6) stores/combatStore.ts > stores/gameStore.ts > stores/gameActions.ts > stores/skillStore.ts
+8. 7) stores/combatStore.ts > stores/gameStore.ts > stores/gameLoopActions.ts
+
+## How to fix
+1. Identify which import in the chain can be extracted to a shared types/utils file.
+2. Move the shared type or function there.
+3. Both files import from the new shared module instead of each other.
+4. Run: bunx madge --circular src/lib/game  (should return clean)
