0.9.3: Graph from Source on main.archify works again

On a main.archify page in Source, Graph built the Graph page but the
host held it back until Source closed, so nothing happened, and Model
then showed the held Graph page. Switching between the model and its
graph now leaves Source first, and the page forgets Source when Graph
replaces it, so Model on the Graph page comes back to the model.

 # Changelog
 
+## 0.9.3 — 2026-11-04
+
+- Fixed: on a `main.archify` page in Source, **Graph** did nothing, and **Model** then showed the Graph page instead of the model. Graph now leaves Source and opens at once, and **Model** on the Graph page comes back to the model, not to Source.
+
 ## 0.9.2 — 2026-10-27
 
 - **Source view.** Every Archify page can show its file's YAML in place: **Diagram | Graph | Source** on diagrams (the old **Diagram | Graph** switch, now on every diagram; Graph only inside a model), **Model | Graph | Source** on `main.archify`, **View | Source** on registry and decision pages, and Source on the Graph page too. The YAML opens in an editor inside the page, under its toolbar and heading, in the page's own colours: line numbers, folding, brackets, multiple cursors, undo and redo, ⌘S/Ctrl+S saves. Problems are underlined as you type, listed under the editor (click the count to go to the next one) and counted on the **Source** segment, also while the picture shows. Completion and hover come from the schema of the file, with nothing else installed. Edits go to the VS Code document, so the tab's dirty dot, save, Git and the text editor stay in step. **Diagram** (or **Model**, **View**) brings the picture back as it was left; anything rendered meanwhile shows then.
