Sub-Task 5: Mark CraftingTab Design Phase Compatibility (Bug 7) as completed

The fix was already implemented in the repository - the getOwnedEquipmentTypes() function in EnchantmentDesigner.tsx now correctly checks store.equipmentInstances (actual owned items) instead of store.lootInventory.blueprints.

Acceptance Criteria Met:
1. In CraftingTab Design phase, only enchantments compatible with items the player currently owns are shown
2. Compatibility is determined by enchantment type (e.g., weapon enchantments only show if player owns weapons)
3. No performance issues when filtering enchantments (uses Set for O(1) lookups)

Sub-Task 6 (Bug 8) can now proceed as it depends on this.
