Does it have to be the original checksums or will correct checksums
work?  Currently to save time we set all the checksums to
e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855 (an
empty file).

What changed in rust-analyzer 1.82 that made it change? Or was that part
of the error message?

Yes, sorry for being imprecise -- it needs to be the correct checksums,
which in the case of the stdlib seems to be the same as the original
checksums. I suppose if that ever changes we would need to change this
to actually apply re-checksum everything.

Before 1.82, rust-analyzer analyzed the stdlib in a different way, which
didn't require it to run `cargo metadata`, which is the step that fails
here (because cargo bails out with an error if the checksums are wrong).
