Add an option to run scripts without needing to use 'uv run'

[sandenbergmelo]

It would be more practical if uv had an option to run Python files without needing to use the run command explicitly.

Like this:
uv example.py
As an alternative to:
uv run example.py

Sorry, but I don't think we will be doing this. We might add a Python shim that let's you do python example.py (#6265) but uv <file> seems too ambiguous given the amount of other things uv can do.

Another option: if you're on a *nix system you can use a shebang.

Make this the first line of example.py:

#!/usr/bin/env -S uv run

Make sure example.py is executable:

chmod +x example.py

And then run it directly:

./example.py
