Build nav region builder for plan site
Convert the existing buildNavigation() output (NavGroup[]) into a renderable tag tree that can be passed as a layout region to renderFullPage().
Currently the sidebar HTML is hand-rolled in the HTML shell template. This work item replaces that with a buildNavRegion() function that produces serialized tags with BEM classes matching the existing .rf-plan-sidebar__* selectors.
