VMService carried guestWaitForSSH and guestDial fields + matching
constructor args ever since the daemon split, but nothing on
VMService ever read them. The live guest-SSH path runs on *Daemon
(d.waitForGuestSSH / d.dialGuest in guest_ssh.go); WorkspaceService
reaches those through closures wired in wireServices.
So the VMService copies were refactor residue: they made the
service look more decoupled than it actually is, and any future
test that stubbed VMService.guestDial would be stubbing nothing.
Delete the fields, the deps entries, the newVMService assignments,
and the wireServices passes.
Real seams on *Daemon are unchanged — those are the ones tests
(e.g. workspace_test.go) already set directly.
