Build and publish from CI complete example

[davidlrobinson]

First off, thank you for your work on uv. I read in #7475 that one of the intended uses of uv build is the following:

1. Publishing a pure Python package from CI

• Call uv build
• Clear the venv, install the wheel, run a smoke test
• Clear the venv, install the source distribution, run a smoke test
• Call uv publish

The docs mention that a built package can be tested with uv run --with <PACKAGE> --no-project -- python -c "import <PACKAGE>". Is there a complete example demonstrating this in practice from CI?

In addition, can you share an example workflow file for using this with GitHub Actions, or at least a hint? If I am already using the recommended workflow (without the signing steps) for trusted publishing from GHA, do I just replace the build step internals with uv build? I don't think using uv publish is appropriate in that case, correct?
