Status update October 6, 2025

The build-dir was split out of target-dir as part of https://github.com/rust-lang/cargo/issues/14125 and scheduled for stabilization in Rust 1.91.0. 🎉

Before re-organizing the build-dir layout we wanted to improve the existing layout tests to make sure we do not make any unexpected changes. This testing harness improvement was merged in https://github.com/rust-lang/cargo/pull/15874.

The initial build-dir layout reorganization PR has been posted https://github.com/rust-lang/cargo/pull/15947 and discussion/reviews are under way.
