Implement the backend/domain/application changes needed so plugin commands can open a new OS window that hosts a plugin-contributed layout, reusing the existing window pipeline and anti-duplication rules instead of inventing a parallel window system. Scope: extend the accepted view/window surface contract for plugin layout ids, preserve native panel behavior, and keep the window lifecycle compatible with the existing layout/window stores and commands.
