feat(api): implement inventory service with equipment system
...
Add InventoryService for managing character inventory, equipment, and
consumable usage. Key features:
- Add/remove items with inventory capacity checks
- Equipment slot validation (weapon, off_hand, helmet, chest, gloves,
boots, accessory_1, accessory_2)
- Level and class requirement validation for equipment
- Consumable usage with instant and duration-based effects
- Combat-specific consumable method returning effects for combat system
- Bulk operations (add_items, get_items_by_type, get_equippable_items)
Design decision: Uses full Item object storage (not IDs) to support
procedurally generated items with unique identifiers.
Files added:
- /api/app/services/inventory_service.py (560 lines)
- /api/tests/test_inventory_service.py (51 tests passing)
Task 2.3 of Phase 4 Combat Implementation complete.

feat(api): implement Diablo-style item affix system
...
Add procedural item generation with affix naming system:
- Items with RARE/EPIC/LEGENDARY rarity get dynamic names
- Prefixes (e.g., "Flaming") add elemental damage, material bonuses
- Suffixes (e.g., "of Strength") add stat bonuses
- Affix count scales with rarity: RARE=1, EPIC=2, LEGENDARY=3
New files:
- models/affixes.py: Affix and BaseItemTemplate dataclasses
- services/affix_loader.py: YAML-based affix pool loading
- services/base_item_loader.py: Base item template loading
- services/item_generator.py: Main procedural generation service
- data/affixes/prefixes.yaml: 14 prefix definitions
- data/affixes/suffixes.yaml: 15 suffix definitions
- data/base_items/weapons.yaml: 12 weapon templates
- data/base_items/armor.yaml: 12 armor templates
- tests/test_item_generator.py: 34 comprehensive tests
Modified:
- enums.py: Added AffixType and AffixTier enums
- items.py: Added affix tracking fields (applied_affixes, generated_name)
Example output: "Frozen Dagger of the Bear" (EPIC with ice damage + STR/CON)
