/**
 * Returns the migrated value for a given attribute name and its current value,
 * using the same ATTR_WITH_VALUES_TO_REPLACE table as the replaceAttrValues step.
 *
 * Structural migrations (e.g. migrateTextarea, migrateSelect) copy attribute text
 * verbatim from the original template. Since all migrations share one UpdateRecorder
 * and changes are applied in a single commitEdits(), the replaceAttrValues pass
 * cannot patch values that were moved to new positions by a structural migration.
 * Call this function when copying wrapper attributes to apply value replacements inline.
