chore: Flox toolchain and Nix package for nix-darwin - #17
Merged
Conversation
Match go.mod without requiring contributors to install Go, git, gh, and make globally, and keep the module cache inside the environment.
packages.default builds on Linux and macOS. The in-repo Flox env stays a Go toolchain only. Quick start remains clone and make build; Nix is an optional alternative to copying the binary onto PATH.

flox build was taking catalog buildGoModule unpinned while the flake overrode it. Pin in zen.nix so both paths (and a later flox publish) share the same Go 1.25 builder.

Summary
Two optional, separate paths — you do not need both.
Develop (Flox). Flox is a per-project environment.
flox activatein this repo gives you the Go 1.25.7 toolchain plus git, gh, and make, without installing them globally. Module cache stays in the environment. This does not putzenon your system PATH. If you already have Go 1.25+, ignore Flox andmake build.Install (Nix). Nix is a package manager; a flake in this repo describes how to build
