fix(csr): drive tab url restore by announcement, anchor nav submenus

Two mechanisms tried and rejected while testing this against the live showcase, both failing the same way on a second history step: - synthesising a click on the matching tab: a re-render replaces the tab buttons, and clicking a freshly replaced node that has not been bound does nothing at all - tracking the last applied value in the runtime: that state drifts out of step with the component and silently swallows real changes The runtime is now stateless. It announces the value the URL names via a wrnexus:tabs:restore event and the component applies it, comparing against its own selection rather than a DOM attribute a re-render owns. Nav submenus are anchored so the viewport clamp keeps them on screen. Comments in the runtime template trimmed to stay inside the size budget rather than raising the ceiling again. Known limitation: a second consecutive back/forward does not update the selection, because the re-render replaces the component root without rebinding its declarative listeners. That is a framework defect, not a Tabs one, and needs its own fix. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
