Flaky expect failures in resolver

[hauntsaninja]

Getting the following segfault:

thread 'main' panicked at crates/uv-resolver/src/resolution.rs:135:30:
Every package should have metadata

Repro:

In [5]: Counter(subprocess.run("rm -rf .venv; uv venv --seed; uv pip install --no-cache --link-mode=copy --no-deps gpustat==1.1.1", shell=True).returncode for _ in range(100))
Out[5]: Counter({101: 73, 0: 27})

#1583 should improve the error message (I had to do some bisection to narrow it down to a single package)

With #1583 it appears there's some connection to setuptools-scm

Similar message reported in this comment: #1484 (comment)

Awesome, thanks! Will fix.

I can reproduce this on some old commits (I randomly tried c1eb613), but not on main, so I think it's resolved, at least on main? Will re-open if not.

Thank you! I bisected the fix commit to #1607 , hopefully there's something in there that explains the formerly non-deterministic behaviour
