Advanced AI Prompt for Rust/Cargo Optimized CI

Act as a Principal Systems Programmer. Design a highly optimized GitHub Actions workflow for the Rust crate [CRATE_NAME]. The workflow must: 1) Install the minimal required [TOOLCHAIN] profile. 2) Implement aggressive dependency and build caching utilizing `swatinem/rust-cache` to drastically reduce compilation times. 3) Execute `cargo fmt --check` and `cargo clippy` configured to fail the build on any warnings (`-D warnings`). 4) Execute the `cargo test` suite followed by a `cargo build --release` targeting [TARGET_ARCH]. 5) Extract the compiled binary and publish it as a downloadable artifact. Detail how the workflow strictly relies on `Cargo.lock` to ensure absolute build reproducibility.
