Move simulation state and controls into SimulationController - #14

Conversation
The engine, play/pause task, input text and the simulation mode flag move from ContentView @State into an @observable SimulationController. The step delay and highlight mode are read from UserDefaults at each step, as the @AppStorage values were before. No behavior change intended.

- Palette/PaletteActionList.swift: palette rows, drag preview and the action buttons below; actions come in as closures. - Simulation/SimulationDetailView.swift: canvas plus state panel layout for simulation mode, driven by SimulationController. - ContentView keeps the action logic (toggleSimulationMode, openCodeGenerator) and the simulation canvas. No behavior change intended. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Cp4EQgFQyGbM8MVLiWbJKQ

- VisuStructCore: VisuStructDocumentEditing.multiwayAncestorPath and caseIndex(of:inMultiwayAt:), with tests. - Inspector/InspectorElementHints.swift: line editor placeholder and condition hint line per element type. - Remove the unused statementIOModeIfApplicable().

The four export actions in ContentView each rendered the diagram and mapped errors themselves. Export/DiagramExporter.swift now does that; ContentView only stores the share payloads it returns.

- DiagramCanvasView.swift: inputs, state, layout and body, clipboard. - DiagramCanvasDropZones.swift: drop bands, tap insert targets and applying drops. - DiagramCanvasRenderer.swift: Canvas drawing of cells, lines and text. The two new files are extensions of DiagramCanvasView, so members they share lose their `private`. Code is moved unchanged otherwise. No behavior change intended.

Before: ContentView held the simulation engine, the play task, the input text and the simulation mode flag as six
@Stateproperties, plus about 100 lines of play/pause/step/input logic.After: all of that lives in
Simulation/SimulationController.swift. The simulation should behave exactly as before.How:
SimulationControlleris an@Observableclass created with the tabs model, likeDiagramEditorDocumentServices. It moves the step marker by setting the current tab's selection. The step delay and highlight mode are read fromUserDefaultsat each step, the same keys the@AppStorageproperties used. ContentView keepsisSimulationMode,beginSimulationModeandendSimulationModeas one-line forwards. Step 4 of the plan; stacked on #13.Check on Mac and iPad: play, pause, single step, stop; an
input:statement pauses play and resumes after OK; changing the step delay or the highlight mode in the settings while playing; leaving simulation mode keeps a selection.Generated by Claude Code
