### To Reproduce

Run:

asdf install python latest

### Describe the Bug

The version selector sees 3.13.0t as a newer release than bare 3.13.0 and installs it when `latest` is selected (though in my case the default-module installation fails due to dependencies on the crypto limited API, which is unsupported by the freethreading release).

### Expected Behaviour

The -t releasees should be ignored unless the user has set [PYTHON_BUILD_FREE_THREADING=1](https://github.com/edgarrmondragon/pyenv/blob/99fb8bd53b889b648c63e6f8151e73ac6878b116/plugins/python-build/share/python-build/3.14t-dev#L1), or some `ASDF_`-prefixed equivalent var.

Reproduce el problema con `asdf install python latest` en la configuración indicada y, después, sigue la ruta de selección de versiones en el plugin asdf-python. Compara el tratamiento de 3.13.0 y 3.13.0t y comprueba el comportamiento documentado de `PYTHON_BUILD_FREE_THREADING=1`. Se considera completado cuando `latest` ignora las versiones -t de forma predeterminada, pero sigue permitiéndolas cuando se habilitan explícitamente.
