build: invalidate certain cargo-install caches, fixing Win build pt 2

[kgutwin]

I took one last look at the Windows build failure messages, and this is another stab at maybe fixing them. Hopefully invalidating the baptiste0928/cargo-install@v3 caches for cargo-insta and wasm-pack will let Windows rebuild and properly use those tools...

[kgutwin]

so close, looks like just one more cache (cargo-nextest) needs to be invalidated...

I just wiped them all, will try again!

It's so close, now!

Looks like the doctests somehow also need the linker patch.

I'm not sure why setting RUSTFLAGS didn't have any effect on the doctest compilation failure. Cross fingers that the upstream regression gets fixed, then we don't need this. https://github.com/rust-lang/rust/issues/141626#issuecomment-3027216890

@kgutwin windows now seems to pass on main!

[kgutwin]

wait, are you sure? I still see this failure from the most recent "tests" run on main: https://github.com/PRQL/prql/actions/runs/16300971426/job/46035208345

bah you're right! I'm not sure why it shows green here
