errmsg_test.go now invokes the functions that actually emit each
user-visible message (findManifest, verifyRequiredSigner,
collectInputPaths, generateManifestOperation, openManifestReader,
fetchManifestOperation, downloadFile, finishDownload, sanitizePath,
verifyDownloadedHash) and asserts on what they return. No production
format string is restated in the test, so rewording a message now
fails the suite instead of passing against a copied literal.
The signer-mismatch message needs a signed manifest, so it is driven
against one signed by a throwaway gpg key and skipped where gpg is
absent, as the repo's other signing tests are.
Freshen's mtime-presence test now gives the scanned file an epoch
mtime, so an absent manifest mtime misread as the epoch is
distinguishable and the test fails if recordEntry's nil guard is
dropped.
Model: opus-4-8
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.
