The lanes run with CI=1, so the Node island tests require a libnode pack and
fail rather than skip without one. A lane Sandbox prepared from a snapshot
that carries a pack had no way to be told where it is, because the lane
environment pinned only CI, SCRIPTC_SAN and the shard variables. Forward an
explicitly configured SCRIPTC_LIBNODE — a directory inside the Sandbox, never
the host — through sandboxLaneEnv, which every remote lane command already
uses, and document it in the runner's help.
