uv: Installing with `uv` doesn't setup cli entrypoints

Pretty straightforward, I wanted to start using ruff and uv but when I installed uv then ruff I didn’t get a ruff executable as expected. I ended up reinstalling it with pip which setup whatever entrypoint was missing.

I attempted it with another library (pre-commit) and got the same:

$ uv pip install pre-commit
...
$ pre-commit
bash: pre-commit: command not found
$ pip install pre-commit
Requirement already satisfied: pre-commit in /Users/alexander/.pyenv/versions/3.10.7/envs/venv-3.10.7/lib/python3.10/site-packages (3.6.1)
Requirement already satisfied: cfgv>=2.0.0 in /Users/alexander/.pyenv/versions/3.10.7/envs/venv-3.10.7/lib/python3.10/site-package
$ pre-commit

[INFO] Restored changes from /Users/alexander/.cache/pre-commit/patch1708173389-43374.

This is running in a virtualenv setup by pyenv, activated with a .python-version file (so it auto-activates when I enter the folder). I installed uv into the project with pip first.
