Release v4.183.0

Changed

• The Stage runs and renders Scene 4.75.0 (includes the storefront shell bar and indicator button of Scene 4.73.0, from #620 which this carries): a storefront's own shell can put a bar in its topbar and an indicatorButton (the basket count) in it.
• An application toolbar button declared in a navigation topbar region of a layout or module (decision 0098) is carried into Scene's navigation model (NavigationButton: slice written as the qualified id, emphasis, icon, authorize as the policy expression) and drawn by the region, which opens the slice's task dialog over the current page. The converter no longer reports STAGE-SCENE-NAV-001. (Cratis/Scene#215)

Fixed

• The default blueprint's own topbar no longer replaces the topbar a screenplay shell declares (Cratis/Scene#217). Part of #610.

Supersedes #620 (its commits are merged in; the pin is moved on from Scene 4.73.0 to 4.75.0).
