Enhance protocol and simulation features with activity tracking and behavior definitions

- Updated protocol documentation to include new `activity` and `activityLabel` fields in the person card response, reflecting real-time activity status.
- Introduced `BehaviorDef` to define behavior rules, including need thresholds and lesson skill gains, enhancing AI decision-making.
- Revised the `DefCatalog` to incorporate behavior definitions and updated validation logic to ensure proper behavior handling.
- Enhanced the simulation to manage presence and activity states, allowing for more dynamic interactions within the school environment.
- Updated tests to validate the new activity tracking and behavior functionalities, ensuring robust performance and reliability.
- Improved localization strings to support new activity and behavior features, enhancing user experience.
