QuoteMutex
Magento\Quote\Model\QuoteMutex
What it does
This class provides database-level locking for quote operations to prevent race conditions when multiple requests try to modify the same quote simultaneously.
Developers should use this when performing critical quote updates (like checkout or cart modifications) that need to be atomic and thread-safe.
It uses database row locking with transactions to ensure only one process can modify a quote at a time.
