Coming from 10+ years of pip and also heavy venv user - uv seems pretty good. First impressions of uv are quite nice, but how does one change Python versions once you have a project up? I installed 3.13 with `uv python install python3.13` I see bunch of Python versions now with `uv python list` (uv even found my old Anaconda 3.9 install from way back) But how would I switch to 3.13? LLM hallucinates with `uv venv use 3.13` but that command does not work. I see from https://docs.astral.sh/uv/concepts/projects/config/#python-version-requirement https://docs.astral.sh/uv/concepts/projects/config/#python-v... that one can specify the version in pyproject.toml, but should not there be a command line to switch?
