The subprocess import test was creating .tmp-hermes-exec-ask-import/
in the repo root without cleanup. Switch to pytest's tmp_path fixture
so the temp directory is auto-cleaned and never appears as untracked.
Regression tests for silent pending_approval when ask-mode leaks into
interactive CLI, plus a Path-typed hermes_constants mock so the
slash-worker profile_home test survives per-file isolation.
