`release.yml` only runs on `v*` tags, so nothing verifies a commit
before it lands on `main`. `main` is currently red on three of the five
gates `make check` defines, which is the drift this is meant to catch.
Adds a single job running the three Rust gates verbatim as the Makefile
spells them:
cargo fmt --all -- --check
cargo clippy --workspace --all-targets -- -D warnings
cargo test --workspace --all-targets
Conventions follow release.yml so the two workflows stay consistent:
ubuntu-22.04, the same apt packages (the workspace includes
apps/desktop/src-tauri, so even `cargo check` needs webkit2gtk),
dtolnay/rust-toolchain@stable and Swatinem/rust-cache@v2 with the same
`. -> target` workspace key.
