Keep the two invariant tests from #105428: a genuine second instance whose argv is scoped to another HERMES_HOME is not a holder of our state.db; argv that names our state.db stays flagged. The helper-shape tests were change-detectors on `_argv_scoped_to_other_home` internals. The salvaged commit is re-authored to TaoMasterCoder's GitHub noreply identity: the original `devops@77hub.com` is a shared org address (misconfigured local git, not malice). Refs #107440
