feat: add city, diplomacy, general, nation, and helper constraints

- Implemented various constraints for city management including occupied, supplied, and capacity checks. - Added diplomacy constraints to manage relationships between nations. - Introduced general constraints to validate general states and resources. - Created helper functions for reading entities and resolving IDs. - Enhanced the overall logic for managing game state and constraints.
