kUML v0.55.3 — Desktop: dialogs that actually show up, ⌘ shortcuts on macOS

kUML is a Kotlin DSL and toolchain for UML, SysML 2, C4, BPMN and more. This is a Desktop polish release.

• "New Workspace…" and the workspace trust dialog were Compose popups drawn inside the main window. Compose does not paint popups over heavyweight Swing components, and the editor and the SVG preview are exactly that, so the dialogs opened invisibly or cut off. They are real dialog windows now.
• Menu shortcuts were KeyShortcut(ctrl = true) everywhere, and Compose Desktop does not map ctrl to ⌘. Everything goes through one platformShortcut helper now: ⌘ on macOS, Ctrl on Windows and Linux.
• Workspace document header: Read/Edit as tabs above the content, type and title aligned. Scripts saved in an Engineering workspace now appear in the tree (it was scanned only once on open).
