43          ## What?
44
45          Regenerates `gomod2nix.toml` to reflect the current `go.mod` / `go.sum`.
46
47          ## Why?
48
49          Keeps the Nix build in sync with Go module changes. Without this, `nix build` fails when new or upgraded Go deps are missing from `gomod2nix.toml`. Generated automatically by the gomod2nix sync workflow.
