uv incorrectly thinks a 3.13t venv doesn't satisfy >=3.8 #12445
Description
Summary
I'm trying to run the tests for the python bindings for kornia-rs on the free-threaded build and noticed this strange behavior in a folder that has an existing 3.13t venv:
± uv run -v maturin develop -m Cargo.toml
DEBUG uv 0.6.9 (3d9460278 2025-03-20)

Using CPython 3.11.10
IMO this is wrong and uv should pick 3.13t.
To reproduce this with kornia-rs, do:
$ git clone git@github.com:kornia/kornia-rs.git
$ cd kornia-rs/kornia-py
$ just install-dev
$ uv run -v maturin develop -m Cargo.toml
I haven't checked if this happens in a simpler setup.
