gen-gomod 0.1.21

//! Shared M1 fixtures — filesystem-free `go list` stubs driving the
//! encoder through [`MockGoBuildEnv`]. These are the canonical Gate-A
//! shapes (2 mains sharing one internal pure-Go+embed package, std-only
//! deps) + a dep-free single-main, built from `serde_json` so there are
//! no hand-format escaping bugs.
