refactor: split bloated state types into State + Actions interfaces (issue #102)

- CombatState: split into CombatState (data) + CombatActions + CombatStore
- PrestigeState: split into PrestigeState (data) + PrestigeActions + PrestigeStore
- ManaState: split into ManaState (data) + ManaActions + ManaStore
- GameState: deprecated, removed from barrel exports
- crafting-actions: updated to use CraftingState instead of GameState
- combat-utils/mana-utils: replaced Pick<GameState,...> with focused interfaces
- DisciplineCardProps: split into Definition + Runtime + Callbacks
- stores/index.ts: now exports both State and Actions types
