Follow-up to #25: v0.5.7 made rendering a page without a layout work, but Vue still warns on every page.

LayoutSlot and LayoutSlotsForward call inject(injectionKey) with a single argument, and Vue warns whenever the key is missing and no default was passed (it checks arguments.length > 1), so every mounted page logs injection "Symbol(dxup:layout-slots)" not found. useLayoutSlots() a few lines above already passes null.

I'm not sure if we should do this since normally named slots declared for a layout don't belong to the page itself. Is it possible to consider rendering slots on the page component's parent component when there is no registry? (not sure if it's possible)

Fair, I'm not attached to the second commit.

I asked Claude to try your idea. Its findings:

Pushing the named slots onto getCurrentInstance().parent.slots from the forward renders <header>empty</header><main><div>page</div></main> on SSR — the parent renders before the child's setup runs, and SSR is a single pass. On the client it would need a forced re-render of the parent, which then disagrees with the hydrated output; that part is reasoning, not a test.

The registry works because an ancestor provides it and a descendant consumes it, and on the server LayoutSlot can await ready through Suspense. A page's parent is neither, so it would have to implement the registry contract itself — not something RouterView or mountSuspended can be expected to do.

What I'm after is simpler: I want to unit test pages without hand-written wrappers in every spec. This patch may well be the wrong shape for it — it does make the page render markup that isn't its own.

Maybe it belongs in @nuxt/test-utils instead: something that kicks in only when namedLayoutSlots is enabled and mounts a page the way the app renders it, so mountSuspended(Page) matches production on its own.

The first commit is independent of all this — I can keep just that one in this PR and move the slots part to a separate issue.

Yes, just keep the first commit for now.

Done. I also created issue #30.
