Enhancement: Implement automatic registry rollback on execution failure #612

Currently, if the script fails or encounters an unhandled exception during the execution of debloat parameters, the registry is left in a partially modified, inconsistent state.

This enhancement wraps the execution loop in a try-catch block. If an execution failure occurs, the script automatically loads the pre-execution registry backup (created via New-RegistrySettingsBackup) and restores the registry to its original state, ensuring transactional integrity.
