Enhance AI and simulation components with presence management and routing capabilities

- Introduced the `HSchool.Ai` project, responsible for routing, day plans, and presence management.
- Updated the `HSchool.Simulation` project to integrate with the new AI functionalities, improving decision-making and presence tracking.
- Added `travelMinutes` to room and territory definitions, ensuring accurate movement calculations within the simulation.
- Enhanced the `School` class to manage presence and implement empty-time skipping functionality.
- Updated documentation to reflect the new AI features and their impact on school simulation.
- Added tests for presence management and routing to ensure robust functionality and reliability.
