2.1.0 - self-contained Rust supply chain Adds rust-lint, rust-release-binary, rust-sbom, rust-crates-publish templates so a Rust CLI consumer can ship a fully-signed, cross- compiled release through the dunn.dev catalog without depending on any external catalog. ci-rust image expanded: Rust 1.95 base, clippy + rustfmt rustup components, standalone zig 0.13.0, cargo-zigbuild 0.22.2, aarch64-apple-darwin and aarch64-unknown-linux-gnu rustup targets, Phracker MacOSX 11.3 SDK mounted at /opt with SDKROOT exported. Cross-compile picks zig-as-linker for darwin/arm64 + linux/arm64 (no nested docker required; one image, one toolchain). linux/amd64 is plain cargo build. parallel:matrix shape mirrors go-release-binary. The supply-chain components (slsa-attest, release-create, container-image) are language-agnostic and compose with rust-release-binary the same as with go-release-binary. See CHANGELOG.md for the full migration shape and consumer example.
