Update to nightly-2026-04-16 (#822)

We are pretty far behind, so let's update!

The main migration was that `file_depinfo` got removed in
https://github.com/rust-lang/rust/pull/153778/changes

Other than that, not much. Took me a while to figure out that the huge
linker error I got was due to the fact that my tmp dir had not enough
space left for all the artifacts xD

One i set a custom `TMPDIR` it worked like a charm.

Closes #832
