w:sdt block-level structured document tag

A block w:sdt surrounds one or more block-level structures and orders its properties, optional end properties, and content under the CT_SdtBlock model. safe-docx preserves an unchanged direct w:body/w:sdt as one scaffold-owned boundary during forced rebuild and reconstructs controlled paragraphs for a block control directly inside w:tc. Exact subtree/wrapper preservation is a bounded metamorphic invariant rather than a requirement imposed by ECMA-376.
