* Create rust.yml

* ci(workflow): add Rust formatting and enhance build steps

- Introduced a new job `fmt` to check code formatting with `rustfmt` in the GitHub Actions workflow.
- Updated the `build` job to depend on the `fmt` job, ensuring code is properly formatted before building.
- Added steps to install Clippy and run it with `--deny warnings`.
- Set up installation and build steps for `gtk4-layer-shell` dependencies using Meson and Ninja.
- Changed build command to `cargo build --release` for optimized builds.

* Update rust.yml
