- Add `persistence.rs` for stable serialization of dock layouts without runtime identifiers. - Introduce `preview.rs` for geometry handling of dock drop previews. - Create `sizing.rs` to manage content-aware sizing policies and constraint solving for dock panels. - Implement `welcome.rs` to provide a welcome surface when no documents are open, featuring New and Open actions.
