- Introduced ServerLogger for logging startup steps and world I/O operations. - Implemented ServerProperties for loading and saving server configuration from `server.properties`. - Added WorldManager to handle world loading and creation based on server properties. - Updated ServerMain to integrate server properties loading and world management. - Enhanced project files to include new source and header files for the server components.
