SaveHandler
Magento\Catalog\Model\Category\Link\SaveHandler
What it does
This class handles saving category assignments and positions for products in Magento 2.
It acts as an extension handler that processes category links when a product is saved, merging new category assignments with existing ones and updating their positions.
Developers typically don't interact with this class directly as it's automatically invoked during product save operations through Magento's entity manager system.
