ci: build + publish Rust CLI binaries for all platforms on release (#8)

Add .github/workflows/rust-release.yml: on a v* tag (or manual dispatch),
cross-build the faker2 CLI for Linux x86_64/aarch64 (gnu + musl), macOS
Intel/Apple-Silicon and Windows, then attach the archives + sha256 checksums
to the GitHub Release. Uses default features (self-contained, no dataset).
