Walkthrough

Updated GitHub Actions CI workflow to pin the dtolnay/rust-toolchain action to a specific commit hash instead of floating tags, and added explicit toolchain: stable parameters to relevant jobs. The miri job retains its dynamic nightly channel configuration.

🐰 A rabbit pins down the toolchain's spring,
No more shall versions dance and fling!
