JackDoanandClaude Fable 5.1 8713d4acb1 windows: Disable DAD and router discovery on the ipv6 interface
Follow-up to #1871, which put a handle on the v6 interface for the first time.

Nothing answers on the far side of the adapter but nebula, and nebula drops the probes. Duplicate address detection only holds the overlay address tentative for a round it can never lose, and router solicitations leave for a multicast group nebula has no host for. Both come off on the v6 handle, the same treatment wireguard-windows gives its adapter.

The v4 handle is untouched: the adapter has no link layer for ARP-based conflict detection, and #1871 deliberately left the v4-only path alone.

Smoke asserts DadTransmits=0 and RouterDiscovery=Disabled on the v6 interface.
