ProcessingErrorAggregatorInterface

What it does

This interface defines the contract for aggregating and managing errors during Magento 2 import/export operations.

Developers use implementations of this interface to collect validation errors, track invalid rows, apply error-handling strategies (skip or stop), and retrieve error details for reporting.

It's essential for controlling import behavior when data quality issues are encountered.
