Add option to auto-activate uv

Shouldn't that be on by default?

I just mimicked the options of poetry, uv environment does not need to be active, one can always use it via uv run python something is just not very ergonomic.

Now I'm double-checking the code, and maybe the problem happens because the task to sync uv, happens before the one for activating venv? that would explain why uv is not using the correct python (it is lacking the libraries defined in libraries).

Can you provide a way to reproduce the issue?

FWIW, I get around this with using venv to create the virtual environment, and then uv just reuses that environment

  languages.python = {
    enable = true;
    package = pkgs.python312Full;
    venv.enable = true;
    uv = {
      enable = true;
      sync.enable = true;
    };
  };
