Subject: [PATCH] Add failing incomplete markers scenarios (#200)

We're currently (https://github.com/astral-sh/uv/issues/4732) failing to
install `c` from the added scenario:

```
$ echo "fork-incomplete-markers-8137fed5" | uv pip compile --index-url http://127.0.0.1:3141 -p 3.9 --universal -
Resolved 4 packages in 38ms
# This file was autogenerated by uv via the following command:
#    uv pip compile -p 3.9 --universal -
fork-incomplete-markers-8137fed5==0.0.0
fork-incomplete-markers-a-8137fed5==1.0.0 ; python_version < '3.10'
    # via fork-incomplete-markers-8137fed5
fork-incomplete-markers-a-8137fed5==2.0.0 ; python_version >= '3.11'
    # via fork-incomplete-markers-8137fed5
fork-incomplete-markers-b-8137fed5==1.0.0
    # via fork-incomplete-markers-8137fed5
```

This is one particular scenario that we need to test for solving
https://github.com/astral-sh/uv/issues/4732

I had to update the lockfile for the recent uv lockfile changes, split
out to #199 which removes it from the diff here.

+The root cause the resolver to fork over `a`, but the markers on the variant
+of `a` don't cover the entire marker space, they are missing Python 3.10.
+Later, we have a dependency this very hole, which we still need to select,
+instead of having two forks around but without Python 3.10 and omitting
+`c` from the solution.
