Closes https://github.com/astral-sh/uv/issues/14874 Closes https://github.com/astral-sh/ruff/issues/23402 uv has fairly extensive test coverage for this functionality but it seems challenging to copy it over My smoke test strategy was to ask an LLM to build the wheel and test all of the cases ``` $ uv build --wheel Building wheel...
