Module driver 

Database driver traits and capability descriptions. Database driver interface for Toasty.

This module defines the traits and types that database drivers must implement to integrate with the Toasty query engine. The two core traits are [Driver] (factory for connections and schema operations) and Connection (executes operations against a live database session).

The query planner inspects [Capability] to decide which [Operation] variants to emit. SQL-based drivers receive [Operation::QuerySql] and [Operation::Insert], while key-value drivers (e.g., DynamoDB) receive [Operation::GetByKey], [Operation::QueryPk], etc.
