KiCadRoutingTools

"""Path bootstrap for the standalone tools (#522 layout).

The engine modules these tools import (kicad_parser, routing_defaults, ...)
live in ../py_router. Import this FIRST in every py_tools script:

    import _path  # noqa: F401

Running `python3 py_tools/<tool>.py` puts py_tools/ at sys.path[0], so this
module always resolves; it then makes the engine importable flat.
