Nanobrew: The fastest macOS package manager compatible with brew

Nanobrew is a macOS package manager written in Zig, claiming to be 7,000x faster than Homebrew. It achieves speed through concurrent downloads/extraction/dependency resolution, copy-on-write materialization, SHA256-keyed deduplication, and replacing curl subprocesses with Zig's native HTTP client—all in a single ~2MB binary with no Ruby runtime.
