CartMutexInterface

What it does

This interface defines a mutual exclusion (mutex) mechanism for cart/quote operations in Magento 2.

Developers use this to prevent race conditions when multiple requests attempt to modify the same shopping cart simultaneously, such as during checkout or when adding items to cart.

It ensures that only one process can modify a quote at a time by locking it, executing the operation, and then releasing the lock.
