homebrew: turn go install into a formula

♠ Previously. Problem statement: meat only documents a go install command, but I want Homebrew to manage it1. The existing installation lived under $GOPATH: % go install meat.dev/cmd/meat@latest % which meat /Users/thiago.perrotta/go/bin/meat There are no tags or releases. @latest currently resolves to a Go pseudo-version: % go list -m -json meat.dev@latest { "Path": "meat.dev", "Version": "v0.0.0-20260803201634-f39f41dfe7b5", "Query": "latest", "Time": "2026-08-03T20:16:34Z", "Dir": "/Users/thiago.perrotta/go/pkg/mod/meat.dev@v0.0.0-20260803201634-f39f41dfe7b5", "GoMod": "/Users/thiago.perrotta/go/pkg/mod/cache/download/meat.dev/@v/v0.0.0-20260803201634-f39f41dfe7b5.mod", "GoVersion": "1.24.13" } The pseudo-version gives us commit f39f41dfe7b5; the module’s vanity import page points at github.com/boldsoftware/meat.
