crates_universe does not rerun when Cargo.* files change

[gferon]

I ran across this issue in our CI setup, where the Bazel daemon is running from a previous build. It turns out that when using a combination of Bazel 8.0.1 and rules_rust 0.57.1, changes to Cargo.toml and Cargo.lock files listed in crate.from_cargo are not picked up.

I made a very simple example repo here to show the problem in action: https://github.com/gferon/rules_rust_no_refresh_bug (see the ./build-refresh-build.sh script at the root).

This also happens when switching branches with git.
