Engine.PeerForIP was pure delegation to the callback that LocalBackend installs via SetPeerForIPFunc, so external callers going through the engine were taking a pointless round trip: LocalBackend called b.e.PeerForIP, which called right back into LocalBackend, and the netstack UseNetstackForIP hooks in tsnet and tailscaled did the same dance one layer removed. Export LocalBackend.PeerForIP and make those callers use it directly. The engine-internal cold paths (Ping, TSMP disco advertisements, pendopen diagnostics) still need the lookup and have no netmap of their own, so SetPeerForIPFunc stays on the interface, but the lookup method itself is now unexported and gone from the Engine interface. In tailscaled the UseNetstackForIP hook moves from netstack setup to just after the LocalBackend is created, since the backend doesn't exist yet when netstack is wired up.
