Signed Caveman runtime companions for macOS, Linux, and Windows. The binaries are licensed under the Apache License 2.0 (LICENSE, NOTICE); see LICENSING.md and the attached third-party notices. The ghcr.io caveman-proxy image is still built without cgo, so its code compressor handles Go source only; the caveman-proxy and caveman-engine binaries here also compress TypeScript, JavaScript, Python, Rust, Java and C/C++.
