feat: Add Enhanced Input Manager for context management and key rebinding
- Implemented USS_EnhancedInputManager to manage input contexts with priority. - Added methods for pushing, popping, and querying input contexts. - Integrated input mode switching and key rebinding functionality. feat: Introduce Inventory System Component for item management - Created UBPC_InventorySystem to handle inventory operations such as adding, removing, and sorting items. - Implemented weight management and slot organization features. - Added event dispatchers for inventory changes. feat: Develop Item Data Asset for item definitions - Established UDA_ItemData as a base class for all items, encapsulating properties like type, weight, and stack limits. - Included conditional sub-data structures for equipment, consumables, and inspect data. feat: Create State Manager Component for player state management - Developed UBPC_StateManager to manage player action states and overlays. - Implemented gating logic for action requests and vital sign tracking. feat: Implement Save Manager for game state persistence - Introduced USS_SaveManager for handling save/load operations and slot management. - Utilized FArchive for efficient binary serialization. feat: Implement Damage Reception System for combat mechanics - Created UBPC_DamageReceptionSystem to process incoming damage and apply resistance calculations. - Added event dispatchers for damage reception and hit reactions.
