Add DynastAI game environment with FastAPI backend and web frontend

- Introduced `dynastai_local_server.py` for local development and testing.
- Implemented `dynastai_server.py` as the main server entry point.
- Created FastAPI endpoints for game state management, card generation, and player choices.
- Developed a web interface with HTML, CSS, and JavaScript for user interaction.
- Added game logic for managing metrics and decision effects.
- Included configuration management and utility functions.
- Established a testing framework for API and environment functionality.
- Updated README.md with project overview and setup instructions.
