"""pytest configuration — ensure ``scripts/`` is importable via package syntax.

The ``scripts`` directory is a PEP 420 implicit namespace package (no
``__init__.py``).  Because ``uv run pytest`` does **not** add the project root
to ``sys.path``, ``from scripts.sweep_cam_perf import ...`` would otherwise
fail with ``ModuleNotFoundError``.

This conftest inserts the repository root at the front of ``sys.path`` so that
``scripts`` is discoverable as a top-level package.
