## Summary
This PR adds a release workflow powered by `cargo-dist`. It's similar to
the version that's PR'd in Ruff
(https://github.com/astral-sh/ruff/pull/9559), with the exception that
it doesn't include the Docker build or the "update dependents" step for
pre-commit.
Each cache entry is ~1 GB of our allotted 10 GB for the repository which
is quite a bit. We're probably losing cache entries all the time since
we add an entry per commit per pull request.
Saving the cache takes ~3 minutes
([example](https://github.com/astral-sh/puffin/actions/runs/7479909295/job/20358124969)),
it's probably just slowing down CI. It's ~25% of our test runtime and
~50% of our clippy runtime.
