Hi,

this small patch series introduces some improvements for our Rust
infrastructure. Most importantly, it introduces a couple of static
analysis checks to verify consistent formatting, use Clippy for linting
and to verify our minimum supported Rust version.

Furthermore, this series also introduces support for building with Rust
enabled on Windows.

The series is built on top of 45547b60ac (Merge branch 'master' of
https://github.com/j6t/gitk, 2025-10-05) with ps/rust-balloon at
e425c40aa0 (ci: enable Rust for breaking-changes jobs, 2025-10-02) and
ps/gitlab-ci-windows-improvements at 3c4925c3f5 (t8020: fix test failure
due to indeterministic tag sorting, 2025-10-02) merged into it.

Thanks!

Patrick
