golangci-lint 2.12 deprecated `gomodguard` in favour of `gomodguard_v2` and printed a warning on every `make check`. `.golangci.yml` now disables the old name, the same way it already handles `wsl` and `wsl_v5`. With `linters.default: all` the replacement was already enabled, so what is checked does not change; only the warning goes.
Model: opus-4-8 (implementation, review); fable-5-1 (merge message)
The module, the script entrypoints and Makefile, Docker-only linting, the mnemonic sources in the specified order with their refusals, the BIP-85 derivation, and keyfunc ssh pub and priv with the README test vectors as tests. Two review rounds; the second passed with no findings.
