feat: add keybinding manager for customizable action shortcuts
Implement KeybindingManager singleton class to support: - Storing and loading keybinding configuration from ini files - Querying whether an action's keybinding was pressed - Runtime rebinding of actions to different keys - Default keybinding set: C=Character, I=Inventory, S=Spellbook, K=Talents, L=Quests, M=Minimap, Esc=Settings, Enter=Chat This is the foundation for user-customizable keybindings. Integration with UI controls and replacement of hard-coded ImGui::IsKeyPressed calls will follow in subsequent improvements.
