"""Repo-root conftest: loads pytest-homeassistant-custom-component explicitly.

The plugin autoloads via a pytest11 entry point on every pytest run once
installed, but importing it on Windows fails immediately (imports `fcntl`,
Unix-only) before any test collects. `-p no:homeassistant` in pyproject.toml
blocks that autoload; this file loads the plugin back explicitly, with
Windows compatibility shims applied first. pytest only honors
`pytest_plugins` in the rootdir conftest, so this cannot live in
tests/conftest.py.
