add the project metadata a published package needs

The package declared no authors, no URLs, no classifiers and no
keywords, so a PyPI page for it would be blank and it would not turn up
in a search. Fill those in.

Contributors are listed by name only. They are the same people the
README credits, so this discloses nothing new, and publishing other
people's email addresses to PyPI is not ours to decide.

Also mirror the dev dependencies into [project.optional-dependencies].
[dependency-groups] is PEP 735, which only uv reads, so there was no way
for a pip user to install what the tests need; `pip install -e '.[dev]'`
now works. The two lists have to be kept in step by hand.
