Two failures on the branch, neither on macOS, which is why they surfaced
only in CI.
`cargo deny` rejected `unicode_names2`, which `ruff_python_parser` pulls in
and which carries `Unicode-DFS-2016` alongside its MIT/Apache dual licence.
That licence covers the character tables and is the older wording of
`Unicode-3.0`, already on the allow list; added beside it.
The two new config-discovery tests asserted on `../project/.jscpd.json`,
and Windows prints the separator it joined with, so both failed there.
They now normalise backslashes before comparing — the assertion is about
which file was read, not about how the path is spelled.
