The first wired slice of relationship visualization (V1). `show relationship <name>` now renders the relationship as two full structure boxes joined by a width-jogging connector (child-left / parent-right, n…1 cardinality, on delete/update actions), styled App-side, with a vertical-stack fallback for narrow terminals. - db.rs: RelationshipDiagramData + show_relationship worker path (structured data: the relationship + both endpoint TableDescriptions) - runtime.rs: named relationships route to the structured outcome (boxed); other show <kind> forms stay prose - app.rs/event.rs/ui.rs: DslShowRelationshipSucceeded rendered App-side; new diagram OutputStyleClass variants; App::last_output_width from ui.rs - output_render.rs: styled Seg layout engine (boxes, connector routing, side-by-side + vertical), composing the ADR-0016 box primitives Tests: 4 unit + 4 integration; full suite 2201 pass / 0 fail / 1 ignored; clippy nursery clean. requirements.md V1 stays [/] (show table diagrams, compound routing, DDL-echo wiring remain).
