- Add feature flags: hi-fidelity-tables, hi-fidelity-styles, hi-fidelity-lists, hi-fidelity-sections
- Tables: inject true w:gridSpan/w:vMerge and w:tblGrid widths via post-build XML when enabled
- Styles: ensure TableHeader style in styles.xml; tag first row when headers present
- Lists: robust numbering.xml for ordered/unordered with multi-level definitions
- Sections: write tail w:sectPr with page size/orientation/margins
- Tools: expose new operations (sections, list items, images, hyperlinks, props, redaction, storage)
- Converters: add preference-aware methods for hi-fidelity export paths; HTML export tool
- Tests: add golden XML assertions gated by feature flags; keep default build green
This enables high-fidelity DOCX output while keeping pure-Rust paths by default.
