Summary

See https://github.com/astral-sh/uv/issues/16951

We should be able to suggest a resolution here

Example

error: Failed to parse: `pyproject.toml`
  Caused by: TOML parse error at line 4, column 19
  |
4 | requires-python = ">=3.14t"
  |                   ^^^^^^^^^
Failed to parse version: after parsing `3.14`, found `t`, which is not part of a valid version:
>=3.14t
^^^^^^^

hint: `requires-python` cannot include a free-threaded selector, consider using `uv python pin 3.14t` instead
