PR Summary

• Removal of $commandClass property from Connection class
  This update removes an outdated feature in the 'Connection' class. Previously, this feature was responsible for creating new commands for the database. However, this task is now managed more efficiently by another part of the code ($commandMap property) and has improved our system's overall performance. It is an important step towards simplifying our code and minimizing deprecated features.
