Some checks failed
check / check (push) Has been cancelled
Adopts golangci-lint v2.12.2 and the canonical .golangci.yml (default: all), and fixes all resulting findings across the tree. Two intended behavior changes: absent MFFilePath.Mtime is handled explicitly in freshen, list and export rather than dereferenced (main panicked); gpg positional key IDs now follow an explicit -- end-of-options marker. All twelve reworded user-visible error messages restored to byte-identical parity with main and pinned by tests.
