set Clean
Marks this PlayerData instance as clean (not modified).
This method is called by the persistence system after successfully saving data to the database. It resets the dirty flag, indicating that the current in-memory state matches the database state.
System Usage: This method is primarily called by the CorePlugin's save operations and should rarely be called by external code. Incorrect usage can lead to data loss by preventing necessary database saves.
When It's Called:
After successful database save operations
After loading data from the database
During data initialization
Warning: Calling this method incorrectly can result in modified data not being saved to the database. Only call if you're certain the data has been properly persisted or if you want to discard pending changes.
