Overview

Converts eengine comparison XML to Expressir::Changes::SchemaChange.

Pure converter: takes XML content as a string (no I/O). The caller is responsible for reading the file. This keeps the object cheap to construct and easy to test in isolation — no fixture file required just to instantiate.
