- Registered a cleanup function for simulation processes to ensure proper termination on server shutdown. - Improved logging during application startup to confirm the registration of the cleanup function. - Updated simulation preparation checks to clarify the conditions for considering a simulation ready, enhancing error handling and user feedback. - Added detailed logging for simulation status changes, improving traceability during the simulation lifecycle. - Introduced new files for simulation configuration and profile data, supporting enhanced testing and visualization capabilities.
