Moves PEP 621 metadata from `setup.py` and `requirements*.txt` into the
`[project]` table of `pyproject.toml`. This enables using hatch as a
task runner for the project, where previously one would need to remember
a bunch of different commands, or repeatedly consult the readme's
developer guide to find all of the relevant commands.
This creates the following hatch commands:
- docs
- fixtures
- format
- lint
- test
- typecheck
It also updates all of the github actions workflows to use the
appropriate hatch commands, and the readme's developer guide, so that
there is only one source of truth for what constitutes running tests.
The "test" workflows now drop the matrix distinction between "pure" or
"native", and run tests in both modes from a single build.
