v0.37.0

Suite-level fixtures (config.suite.setup / config.suite.teardown): shell command(s) run once around run --all — setup before the first scenario, teardown after the last (always) — the beforeAll/afterAll analogue for a shared fixture DB or stub. A failing suite.setup aborts before any scenario runs; a failing teardown warns. Per-scenario setup/teardown still handle per-test state.
