"""#382 E7: pytest scaffolding (forward-looking).

The existing 127 test scripts are bare `if __name__ == "__main__": sys.exit(main())`
programs run by tests/run_all.py (and directly). They keep working unchanged --
this file only sets up NEW pytest-style tests written as `def test_*` functions:

- puts the repo root (and rust_router/) on sys.path so a pytest test can
  `import kicad_parser` / `import synth` without the per-file sys.path hack;
- registers the `integration` marker (`@pytest.mark.integration` for tests that
  shell out to a CLI / route a real board);
- adds `--fast`, which deselects integration-marked tests (mirrors
  run_all.py --fast).

Note: pytest is optional and may not be installed; run_all.py is the primary
runner. This file is inert unless pytest is used.
