test(dogfood): the multi-org probe resolves its host from the package root

Under the per-file temporary cwd, probeOrganizations() defaulted its host
root to that temp directory, so its skip text told the reader to declare
@objectstack/organizations in a /tmp directory's package.json (measured).
The module-level probe now passes this package's root, resolved from the
module's own location.
