Add GetCertificate() and StatusWithoutPeers() ?


https://github.com/tailscale/tailscale/blob/v1.86.4/client/local/local.go#L1152-L1160

is deprecated but not present here (found it in 	"tailscale.com/client/local" but that pulls in a lot of tailscale I don't need including the go line bumps)

likewise

https://github.com/tailscale/tailscale/blob/v1.86.4/client/local/local.go#L706-L707

which I need to get the domain suffix
