Applied, thanks!

I added two follow-ups on top, as there can be multiple RA default
routes, one per receiving interface, like Gabriel mentioned:

- record all IPv6 default routes in the run-env, as query_routes()
  kept only the first one per IP version, so consumers could not tell
  whether a specific interface received its default route through an
  RA.

- skip the RA-received gateway only if the management interface itself
  got it, as a same-gateway RA route seen only on another interface
  would otherwise suppress the static gateway for an interface that
  never receives RAs itself, for example with RA guard active on its
  switch port, leaving the installed system without an IPv6 default
  route.
