uv created a new venv instead of using the one I was already in

[antonysouthworth-halter]

asdf local python 3.12.5
python -m venv venv
. venv/bin/activate
uv add ruff # <- this creates a new venv at .venv?? Why??

uv version:

$ uv --version
uv 0.4.0 (d9bd3bc7a 2024-08-28)

my machine

$ uname -a

(yes, I know this is documented behaviour at https://docs.astral.sh/uv/concepts/projects/#project-environments, but if I ran into this issue I am betting others will end up here as well)
