Version File is fine i guess, but what is all the fuss about the python install. why did you change that?

UV_PYTHON_INSTALL_DIR="/usr/local/bin" PYTHON_VERSION="3.14.6" setup_uv command does not install the specified python version if uv is up to date.

I was planning to open a new issue about this.
