pub fn into_transactional(queries: Vec<Self>) -> Vec<Self>
Wrap each backend’s full plan statement stream with transaction boundaries.
SQLite’s no-DROP-CONSTRAINT temp-table rebuild pattern is canonical; wrapping
the ordered create-temp/insert/drop/rename/reindex sequence in a transaction
protects it from mid-sequence failures. MySQL accepts BEGIN/COMMIT, but
most DDL implicitly commits and is not transactional on that backend.
