1.0.0-alpha.5 breaks `scrollBehavior: 'smooth'`

I'll try to provide more details soon

Closing this as understood on our side.

Root cause:
waku 1.0.0-alpha.5 changed hash-only router.replace() behaviour to scroll by default. In our case we sync the visible OpenAPI section back into the URL hash while the user scrolls, so those observer-driven hash updates started triggering router-managed scroll and caused the page to bounce/jump.

What we changed locally:
we now call router.replace(..., { scroll: false }) for observer-driven hash sync, which keeps the hash updated without fighting manual scrolling.
