`cargo-sweep` issue with Rust 1.85.0

[JohnCMoon]

Using this library, after upgrading to Rust version 1.85.0, I ran into an issue where cargo sweep was removing artifacts that were just built. For example, I have an Earthly job like this:

postgres-unit-test-image:
    FROM +pre-unit-test
    # Build the test binary
    DO rust+CARGO --args="build --tests --release --frozen --offline --features postgres" --output="release/deps/keylay-[^\./]+"
    # Copy the test binary as the container entrypoint
    RUN cp -a ./target/release/deps/keylay-* ./keylay-test
    ENTRYPOINT ["./keylay-test", "--test-threads=1"]

My build began failing at the RUN cp -a line. I noticed in the logs that cargo sweep -i -d was running immediately after the build completed and deleting the binaries that had just been built!

Digging in, I found that in Rust 1.85.0, the hash method used to fingerprint toolchains was modified, so cargo-sweep needed the same update.

I made a PR here that fixes the issue, but since this library has the dependency pinned to 0.7.0, the bug will persist here.

I don't know if the cargo-sweep team is planning on publishing another release soon, but I think this issue will bite anyone using this library with Rust 1.85.0+.

You can work around this issue by installing cargo-sweep yourself from their development branch before doing INIT in this library, but perhaps it would be better to install the fixed commit by default?
