interface StatementInterface

Minimal statement interface for ZTD layer.

This interface defines the contract that all statement adapters must implement to work with the ZTD session. It provides a driver-agnostic API for executing prepared statements and fetching results.

Rows retain the keys and opaque values supplied by the driver. The platform owns value interpretation and SQL encoding.
