/**
 * Relation-to-X++ generator — `generate_object(mode="relation-xpp")`.
 *
 * Ports TRUDUtils "Relation to Xpp": turns a table's relation(s) into ready-to-use
 * X++ — a `select` statement that joins the related table, and an equivalent
 * QueryBuildDataSource/addRange snippet. Field/value constraints are honoured
 * (field == relatedField, and fixed-value constraints become literal ranges).
 *
 * Data source priority mirrors tableInfo: C# bridge (authoritative for relation
 * metadata) → error if unavailable (the symbol index does not carry relations).
 * Output is text X++ the caller pastes into a method body.
