dev: swap black to ruff, drop pre-commit

now that ruff has formatting capabilities, we can drop one more dependency.
This also means that pre-commit is a bit overkill.
Also, the version of black and ruff in the pre-commit config was
out of sync from the version pinned in pdm.lock. That is bad.
So just drop pre-commit, and run stuff manually, there
are only a few commands.

I had to adjust a few of the example docstrings
so that ruff wouldn't autoformat away the needed leading indentation.

I was lazy and just added a bunch of `# noqa: E721` for the
`type(match.value) == str` checks that should be isinstance()
checks, because when I tried isinstance, some tests failed.
The current method isn't that egregious.
