Crate sui_cache 

Built-in binary cache server and push pipeline for sui.

Replaces Attic, Cachix, and nix-serve with a single integrated component. Implements the standard Nix binary cache HTTP protocol (narinfo + NAR).

Architecture

• storage — pluggable storage backends (local filesystem, S3 stub)
• server — axum HTTP server implementing the cache protocol
• signing — ed25519 key management and narinfo signing
• push — pipeline to push store paths to the cache
• gc — garbage collection of unreferenced cache entries
• config — cache configuration types
